[Freedreno] [DPU PATCH v2 0/2] Remove DPU RSC support

MSM display controller hardware (DPU) has an inbuilt RSC block
which can control power resources and bus bandwidth voting
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:

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
