ARM: OMAP3: PM: call pre/post transition per powerdomain

Browse Source 
We only need to call the pre/post transtion methods when we know the
power state is changing.  First, split up the pre/post transition
calls to be per-powerdomain, and then make them conditional on whether
the power domain is actually changing states.
