ARM: OMAP2+: powerdomain/clockdomain: add a per-powerdomain spinlock

Browse source

Add a per-powerdomain spinlock.  Use that instead of the clockdomain
spinlock.  Add pwrdm_lock()/pwrdm_unlock() functions to allow other
code to acquire or release the powerdomain spinlock without reaching
directly into the struct powerdomain.
