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.

This patch introduced a regression where the transition counts for NEON
were no longer accurate because I forgot to call the notifiers for NEON
when calling them for MPU.
The diff below will be folded into this patch before submitting for v3.6.
