iwlwifi: Execute runtime calibration always
Runtime DC calibration was previously conditional. Remove this
behaviour, as new devices support runtime DC calibration,
while older devices ignore the runtime DC calibration request.
This patch addresses low TX throughput issues seen with the 6205.

iwlwifi: don't count the tfds in HW queue any more
Since packets sent to an RA / TID in AGG are sent from a
separate HW Tx queue, we may get into a race:
the regular queue isn't empty while we already begin to
send packets from the AGG queue. This would result in sending
packets out of order.
In order to cope with this, mac80211 waits until the driver
reports that the legacy queue is drained before it can send
packets to the AGG queue. During that time, mac80211 buffers
packets for the driver. These packets will be sent in order
after the driver reports it is ready.
The way this was implemented in the driver is as follows:
We held a counter that monitors the number of packets for
an RA / TID in the HW queues. When this counter reached 0,
we knew that the HW queues were drained and we reported to
mac80211 that were ready to proceed.
This patch changes the implementation described above. We
now remember what is the wifi sequence number of the first
packet that will be sent in the AGG queue (lets' call it
ssn). When we reclaim the packet before ssn, we know that
the queue is drained, and we are ready to proceed.
This will allow us to move this logic in the upper layer and
eventually remove the tid_data from the shared area.

iwlagn: remove calibration knowledge
The init microcode knows very well which calibrations
are required and sends us results for those that are.
Consequently, we can just send all of those to the RT
uCode again.
The problem with having the driver know about this is
that it is a uCode feature, not a hardware feature so
the config is completely unsuitable.
The only thing we need to check is whether the device
needs crystal calibration or not, add a new parameter
to the configuration for that.
This makes new uCode work on 6000 series devices.

iwlagn: remove the callback in host commands
Before this patch, the upper layer could register a callback for each
host command. This mechanism allowed the upper layer to have
different callbacks for the same command ID. In fact, it wasn't used
and the rx_handlers is enough: same callback for all the command with
a specific command ID.
The iwl_send_add_station needs the access the command that was sent
while handling the response (regardless if the command was sent in
SYNC or ASYNC mode). So now, all the handlers receive the host
command that was sent. This implies a change in the handler signature.

iwlagn: move the check_empty logic to the transport layer
This logic is responsible to tell mac80211 when the HW queues are
empty and the BA session can be started / torn down.
Fix a bug on the way:
When the the Tx BA session is stopped and the HW queues aren't empty,
we stop the SW queue to drain the HW queue and then switch to the
legacy HW queue. This is the IWL_EMPTYING_HW_QUEUE_DELBA state.
While in this state, we never wake the SW queue, even when the HW
queue is almost empty, since we need to drain it completely. Look
at iwl_trans_pcie_reclaim regarding this.
Once the HW queue is really empty, we must wake the SW queue in order
to get traffic to the legacy queue.
This step was missing leading to an odd situation were the traffic
would just stall after we tore down a Tx BA session while the HW
queue was not empty.

iwlagn: iwl_tid_data moves to iwl-shared
The rate scaling and the transport need to access the data in
iwl_tid_data, hence the move.
Note that the only component in the upper layer that needs this data
is the rate scaling. Refactoring the rate scaling may help to move
iwl_tid_data from the shared area to the transport area.

iwlagn: iwl-pci doesn't include iwl-dev any more
Move all the iwlXXX_abgn_cfg forward declaration to a separate file
so that iwl-pci.c doesn't need to include iwl-agn.h that includes
all iwl-dev.h
This allows to provide real encapsulation. Dereferencing iwl_priv
in the bus layer will now lead to a compilation error.

iwlagn: bus layer chooses its transport layer
Remove iwl_transport_register which was a W/A. The bus layer knows what
transport to use. So now, the bus layer gives the upper layer a pointer to the
iwl_trans_ops struct that it wants to use. The upper layer then, allocates the
desired transport layer using iwl_trans_ops->alloc function.
As a result of this, priv->trans, no longer exists, priv holds a pointer to
iwl_shared, which holds a pointer to iwl_trans. This required to change all the
calls to the transport layer from upper layer. While we were at it, trans_X
inlines have been renamed to iwl_trans_X to avoid confusions, which of course
required to rename the functions inside the transport layer because of
conflicts in names. So the static API functions inside the transport layer
implementation have been renamed to iwl_trans_pcie_X.
Until now, the IRQ / Tasklet were initialized in iwl_transport_layer. This is
confusing since the registration doesn't mean to request IRQ, so I added a
handler for that.

iwlagn: introduce struct iwl-shared - known by all layers
This struct will hold pointers to all the layers, so that every layer will find
the pointers it needs when calling another layer.
Note that the drv_data set to struct device is now a pointer to
struct iwl_shared.
This solves of bug that I introduced in
iwlagn: simplify the bus architecture
Bug description:
sysfs gets the the driver data from struct device. Till the aforementioned
patch, dev_get_drvdata would return iwl_priv. After the patch, dev_get_drvdata
return iwl_bus which is buggy since the sysfs handlers rely on this value, and
sysfs handlers need iwl_priv.
Now, dev_get_drvdata return iwl-shared. Since we have pointers to all the
layers in iwl_shared, every layer will be able to get the pointer it needs:
bus layer will gets iwl_bus from the PCI suspend callbacks, and the sysfs
handlers will get the iwl_priv they need.
In order to keep good encapsulation, we need to avoid to dereference iwl_priv
from a different layer. This is why instead of including iwl-dev.h from
iwl-shared.h, I added a forward declaration to iwl_priv. Moreover we keep type
safety while providing encapsulation.

iwlagn: introduce iwl-shared.h
It will hold declaration of functions and forward declaration of struct that
are used by several layers.
This will allow modules not to include iwl_priv. iwl_bus and iwl_trans are
still visible to all.
All the layers share the module parameters, move the struct to iwl-shared.h.
Also add all module parameters to iwl_mod_params instead of having them as
global static. This includes
* debug_level
* ant_coupling
* bt_ch_announce
