ARM: 7760/1: cpu_fa526_do_idle: remove WFI
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. Applies to arm-soc/for-next (and 3.10-rc1). Changes since v1: 1. remove WFI but make sure cpu_fa526_do_idle do not fall through to cpu_fa526_dcache_clean_area Note: moxart boots and prints to UART without this patch, but input is broken.
