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