ARM: OMAP2: PM/powerdomain: drop unnecessary pwrdm_wait_transition()
Drop an unnecessary pwrdm_wait_transition() from mach-omap2/pm.c -
it's called by the subsequent pwrdm_state_switch().
Also get rid of pwrdm_wait_transition() in the powerdomain code - there's
no longer any need to export this function.
