usb: rename phy to usb_phy in HCD
The USB PHY member of the HCD structure is renamed to 'usb_phy' and
modifications are done in all drivers accessing it.
This is in preparation to adding the generic PHY support.

usb: host: ehci-msm: Use devm_ioremap_resource instead of devm_ioremap
Using devm_ioremap_resource() API should actually be preferred over
devm_ioremap(), since the former request the mem region first and then
gives back the ioremap'ed memory pointer.
devm_ioremap_resource() calls request_mem_region(), therby preventing
other drivers to make any overlapping call to the same region.

USB: EHCI: make ehci-msm a separate driver
Separate the Qualcomm QSD/MSM on-chip host controller driver from
ehci-hcd host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before Qualcomm QSD/MSM
can be booted with a multi-platform kernel, which is not expected before
3.11.
With the infrastructure added by Alan Stern in patch 3e0232039
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the msm bus glue.
In V5 (arnd):
- add FIXME about missing usb_add_hcd() or usb_remove_hcd() calls
In V3:
- Detailed commit message added here describing why this patch is required.
- Arranged #include's in alphabetical order.
- driver.name initialized hcd_name[] = "ehci-msm" in platform_driver
structure initialization instead of "msm-ehci", which was the reason
why it broke in EHCI USB testing
In V2:
Tegra patch related changes removed from this patch.

USB: EHCI: remove ehci_port_power() routine
This patch (as1623) removes the ehci_port_power() routine and all the
places that call it. There's no reason for ehci-hcd to change the
port power settings; the hub driver takes care of all that stuff.
There is one exception: When the controller is resumed from
hibernation or following a loss of power, the ports that are supposed
to be handed over to a companion controller must be powered on first.
Otherwise the handover won't work. This process is not visible to the
hub driver, so it has to be handled in ehci-hcd.

drivers/usb/host/ehci-msm.c: use devm_ functions
The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
The original code was also missing a call to iounmap(hcd->regs); in the
remove function, so this patch also implicitly fixes a bug.

EHCI: centralize controller suspend/resume
This patch (as1563) removes a lot of duplicated code by moving the
EHCI controller suspend/resume routines into the core driver, where
the various platform drivers can invoke them as needed.
Not only does this simplify these platform drivers, this also makes it
easier for other platform drivers to add suspend/resume support in the
future.
Note: The patch does not touch the ehci-fsl.c file, because its
approach to suspend and resume is so different from all the others.
It will have to be handled specially by its maintainer.

USB: EHCI: Support controllers with big endian capability regs
The two first HC capability registers (CAPLENGTH and HCIVERSION)
are defined as one 8-bit and one 16-bit register. Most HC
implementations have selected to treat these registers as part
of a 32-bit register, giving the same layout for both big and
small endian systems.
This patch adds a new quirk, big_endian_capbase, to support
controllers with big endian register interfaces that treat
HCIVERSION and CAPLENGTH as individual registers.
