Manivannan Sadhasivam a6e2e3522f bus: mhi: core: Add support for PM state transitions 
This commit adds support for transitioning the MHI states as a
part of the power management operations. Helpers functions are
provided for the state transitions, which will be consumed by the
actual power management routines.

This is based on the patch submitted by Sujeev Dias:
