Subject: [PATCH v4 0/7] Add support for GPU DDR BW scaling

This is mostly a rebase of Sharat's patches [1] on the tip of msm-next branch.
Changes compared to v3:
	1. Rebased on top of Jonathan's patch which adds support for changing
	gpu freq through hfi on newer targets. Created patch 1 to make
	this the generic approach of setting gpu freq on newer targets.
	2. As suggested by Rob, left the icc_path intact for pre-a6xx
	GPUs.

As mentioned in [1], these patches have dependency on Georgi's series from
opp/linux-next [2] and also Sibi's patch which adds a helper function to
set and clear ddr bandwidth vote [2].
