Thanks for the merge.

We don't have any further plans of pursuing the concept of regulator
chaining for upstream. After an off-line chat with Mike T, we are
planning on introducing OMAP specific notifier hooks to clock
framework. This should allow us to do the appropriate sequencing
necessary to control AVS, regulators for ABB and PMIC in the right
sequence.
