The AT91CAP9 processor includes the same Static Memory Controller
(SMC) peripheral as the SAM9 processors, but replaces the SDRAM
Controller with a DDR/SDR Controller (DDRSDRC).
This patch splits the existing
include/asm-arm/arch-at91/at91sam926x_mc.h into at91sam9_sdramc.h and
at91sam9_smc.h.
It also adds an at91cap9_ddrsdr.h for the DDRSDRC controller.

On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
the LCD controller. It's controlled by "contrast" registers though.
This patch lets boards declare that they have that kind of backlight
control. The driver can then export this control, letting screenblank and
other operations actually take effect ... reducing the typically
substantial power drain from the backlight.
Note that it's not fully cooked
- doesn't force backlight off during system suspend
- the "power" and "blank" events may not be done right
This should be easily added in the future.

On the at92sam9263ek board, tell the input subsystem about the buttons.
This patch is taken from Andrew Victor's at91 patchset, then updated to
match the latest kernel code and to use labels printed on the board.
Also update the at91sam9261ek buttons to cope with input changes.

Add NEW_LEDs support for the following boards:
- Cogent CSB337
- Atmel AT91RM9200-DK
- Atmel AT91RM9200-EK
- Atmel AT91SAM9263-EK
Mostly based on patch from David Brownell.

On the at92sam9263ek board, tell the MACB driver the IRQ used
by its PHY. This patch is taken from Andrew Victor's 2.6.23-at91
patchset; it matches board schematics. (But it's currently a NOP
since the MACB driver doesn't yet use PHY irqs.)

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().
