Clean up a few different parts of omap_set_pwrdm_state(): - Remove a superfluous call to pwrdm_state_switch(). Not needed unless LOWPOWERSTATECHANGE is used, because the state switch code is called by either clkdm_sleep() or clkdm_allow_idle(). - Add code to wait for the power state transition in the OMAP4+ low power state change. This is speculative, so I would particularly appreciate feedback on this part. - Remove a superfluous call to pwrdm_read_pwrst(). - Update variable names to be more meaningful (hopefully) and precise. - Fix an error path bug that would not place the clockdomain back into hardware-supervised idle or sleep mode if the power state could not be programmed. The documentation for this function still needs major improvements; that's left for a later patch.
