[PATCH] ARM: mm: cpu_fa526_do_idle: remove WFI

[jonas.jensen@gmail.com (Jonas Jensen)]

As it was already suggested by Russell King and Arnd Bergmann ( https://lkml.org/lkml/2013/5/16/133 ), moxart and gemini seem to be the only platforms using CPU_FA526, and instead of pointing arm_pm_idle to an empty function from platform code, it makes sense to remove WFI code from the processor specific idle function.

Note: moxart boots and prints to UART without this patch, but input is broken.
