mlx5: minor fixes (mainly avoidance of hidden casts)
There were many places where parameters which should be u8/u16 were
integer type.
Additionally, in 2 places, a check for a non-null pointer was added
before dereferencing the pointer (this is actually a bug fix).

mellanox: Logging message cleanups
Use a more current logging style.
o Coalesce formats
o Add missing spaces for coalesced formats
o Align arguments for modified formats
o Add missing newlines for some logging messages
o Use DRV_NAME as part of format instead of %s, DRV_NAME to
reduce overall text.
o Use ..., ##__VA_ARGS__ instead of args... in macros
o Correct a few format typos
o Use a single line message where appropriate

mlx5_core: Change optimal_reclaimed_pages for better performance
Change optimal_reclaimed_pages() to increase the output size of each
reclaim pages command. This change reduces significantly the amount of
reclaim pages commands issued to FW when the driver is unloaded which
reduces the overall driver unload time.

mlx5: Support communicating arbitrary host page size to firmware
Connect-IB firmware requires 4K pages to be communicated with the
driver. This patch breaks larger pages to 4K units to enable support
for architectures utilizing larger page size, such as PowerPC. This
patch also fixes several places that referred to PAGE_SHIFT instead of
explicit 12 which is the inherent page shift on Connect-IB.

mlx5: Fix cleanup flow when DMA mapping fails
If DMA mapping fails, the driver cleared the object that holds the
previously DMA mapped pages. Fix this by allocating a new object for
the command that reports back to firmware that pages can't be
supplied.

net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changes
In the previous QUERY_PAGES command version we used one command to get the
required amount of boot, init and post init pages. The new version uses the
op_mod field to specify whether the query is for the required amount of boot,
init or post init pages. In addition the output field size for the required
amount of pages increased from 16 to 32 bits.
In MANAGE_PAGES command the input_num_entries and output_num_entries fields
sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10.
In the pages request event the num_pages field also changed to 32 bits.
In the HCA-capabilities-layout the size and location of max_qp_mcg field has
been changed to support 24 bits.
This patch isn't compatible with firmware versions < 5; however, it turns out that the
first GA firmware we will publish will not support previous versions so this should be OK.

mlx5_core: Implement new initialization sequence
Introduce enbale_hca and disable_hca commands to signify when the
driver starts or ceases to operate on the device.
In addition the driver will use boot and init pages count; boot pages
is required to allow firmware to complete boot commands and the other
to complete init hca. Command interface revision is bumped to 4 to
enforce using supported firmware.
This patch breaks compatibility with old versions of firmware (< 4);
however, the first GA firmware we will publish will support version 4
so this should not be a problem.

mlx5: Add driver for Mellanox Connect-IB adapters
The driver is comprised of two kernel modules: mlx5_ib and mlx5_core.
This partitioning resembles what we have for mlx4, except that mlx5_ib
is the pci device driver and not mlx5_core.
mlx5_core is essentially a library that provides general functionality
that is intended to be used by other Mellanox devices that will be
introduced in the future. mlx5_ib has a similar role as any hardware
device under drivers/infiniband/hw.
