OMAP2/3: GPIO: generalize prepare for idle
Currently, the GPIO 'prepare' hook is only called when going to
off-mode, while the function is called 'prepare_for_retention.' This
patch renames the function to 'prepare_for_idle' and calls it for any
powersate != PWRDM_POWER_ON passing in the powerstate.
The hook itself is then responsible for doing various preparation
based on the powerstate.
