[PATCHv5 14/14] arm: omap: pm: wait for domain wakeup if changing state of idle domain

[Tero Kristo]

If we are switching the state of an idle powerdomain, we must wait for
the wakeup to complete before attempting to switch to the new state,
otherwise the powerdomain may not be ready for the switch and will fail.
