Support for the at91sam9g20 : Atmel 400Mhz ARM 926ej-s SOC.
AT91sam9g20 is an evolution of the at91sam9260 with a faster clock
speed.
We created a new board for this device but based the chip support
directly on 9260 files with little updates.

This is patch 1 of 2 adding support for the USB High Speed Device Port
on the AT91CAP9 system on chip. The AT91CAP9 uses the same UDPHS IP
as the AVR32 and the AT91SAM9RL.
This patch makes the generic AT91 adaptations, mainly dealing with
the addition of the UDPHS UTMI clock.

Various small at91_udc cleanups:
- Use generic GPIO calls, not older platform-specific ones
- Use gpio_request()/gpio_free()
- Use VERBOSE_DEBUG convention, not older VERBOSE
- Fix sparse complaint about parameter type (changed to gfp_t)
- Add missing newline to some rarely-seen debug messages
- Fix some old cleanup bugs on probe() fault paths
Also add a mechanism whereby rm9200 gpios can drive the D+ pullup
through an inverting transistor, based on a patch from Steve Birtles.
Most UDC drivers supporting a GPIO based pullup should probably have
such an option, but testing it requries such a board in hand!

Modify the UART initialization to allow the board-initialization code
to specify which pins are connected, and which pins should therefore
be initialized.
The current at91_init_serial() will continue to work as-is, but is
marked as "deprecated" and will be removed once the board-specific
files has been updated to use the new interface.
As in the AVR32 code, we assume that the TX and RX pins will always be
initialized.

The AT91 I2C driver is currently marked as "broken" due to hardware
issues. This patch enables AT91-based platforms to also use the
bitbanged GPIO for I2C.
This updates platform setup logic (setting up an i2c-gpio device
using the same pins as the i2c-at91 device, unless only the BROKEN
driver is enabled).
Also make use of the new-style initialization of I2C devices using
i2c_register_board_info().

The Atmel AT91SAM9263 processor includes many more integrated
peripherals than Atmel's previous ARM9-based AT91 processors, so this
has necessitated a few changes to the core AT91 support.
These changes are:
* The system peripheral I/O region we remap has increased from
0xFFFA0000..0xFFFFFFFF to 0xFFF78000..0xFFFFFFFF.
* The increased I/O region forces changes to entry-macro.S and
debug-macro.S due to ARM's limited immediate offset addressing
modes.
* Maximum number of GPIO banks increases to 5.
* 2 MMC controllers so the board-setup code needs to specify which
controller it wishes to use when calling at91_add_device_mmc().

Now that Linux includes support for the Atmel AT91SAM9260 and
AT91SAM9261 processors in addition to the original Atmel AT91RM9200
(with support for more AT91 processors pending), the "mach-at91rm9200"
and "arch-at91rm9200" directories should be renamed to indicate their
more generic nature.
The following git commands should be run BEFORE applying this patch:
git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91
git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91
