ARM: arm-soc fixes for 3.8-rc

People are back from the holiday breaks, and it shows. Here are a bunch of
 fixes for a number of platforms:
  - A couple of small fixes for Nomadik
  - A larger set of changes for kirkwood/mvebu
    - uart driver selection, dt clocks, gpio-poweroff fixups,
      a few __init annotation fixes and some error handling improvement
      in their xor dma driver.
  - i.MX had a couple of minor fixes (and a critical one for flexcan2
    clock setup)
  - MXS has a small board fix and a framebuffer bugfix
  - A set of fixes for Samsung Exynos, fixing default bootargs and some
    Exynos5440 clock issues
  - A set of OMAP changes including PM fixes and a few sparse warning
    fixups
 
 All in all a bit more positive code delta than we'd ideally want to see
 here, mostly from the OMAP PM changes, but nothing overly crazy.

GPIO line that should be set high/low to power off a device
Driver a GPIO line that can be used to turn the power off.
The driver supports both level triggered and edge triggered power off.
At driver load time, the driver will request the given gpio line and
install a pm_power_off handler. If the optional properties 'input' is
not found, the GPIO line will be driven in the inactive
state. Otherwise its configured as an input.
When the pm_power_off is called, the gpio is configured as an output,
and drive active, so triggering a level triggered power off
condition. This will also cause an inactive->active edge condition, so
triggering positive edge triggered power off. After a delay of 100ms,
the GPIO is set to inactive, thus causing an active->inactive edge,
triggering negative edge triggered power off. After another 100ms
delay the GPIO is driver active again. If the power is still on and
the CPU still running after a 3000ms delay, a WARN_ON(1) is emitted.
Required properties:
- compatible : should be "gpio-poweroff".
