Hi Santosh, Kevin,

This series switches Keystone 2 PM code to use Generic PM domains
instead of PM clock domains because of the lack of DT support
for the last.
It will finally allow to enable Runtime PM for Keystone 2.

Patch 1 was reused from [1].

RFC version of patches can be found at [2].

Changes in v2:
- minor comments applied and rebased on top of Linux 3.18-rc1.
