MSM display controller hardware (DPU) has an inbuilt RSC block

based on frame timing parameters w/o DPU driver intervention.
In absence of RSC HW, DPU driver controls these resources.

Downstream driver relies on RSC driver for controlling these
resources (via RSC HW block) for better power benefits.

Since, DPU driver can control these resources, removing RSC
driver support. Corresponding devicetree binding are also removed.

Details for DPU driver upstreaming:
https://lists.freedesktop.org/archives/freedreno/2018-February/001678.html

Changes in v2:
	- Remove last reference to dpu_power_rsc_update
	- Add DPU PATCH tag for better filtering
	- Rebase on tip of for-next-staging

Hi Rajesh,
Unrelated to this change, but I've noticed the threading seems off on the patch sets you're sending. Are you sending the emails one-by-one, or specifying
--no-thread in git send-email?

Sean

Hi Sean,
I had sent the patches one by one, I'll take care of this going forward.

Thanks,
Rajesh
