[DPU PATCH v3 1/2] dt-bindings: msm/disp: Remove DPU RSC device bindings

MSM Display controller includes RSC (Resource Coordinator)
HW block which can control DPU power resources without
DPU driver intervention.
Removing DPU RSC device/driver support till the RSC
dependencies make their way upstream.

-Qualcomm Technologies, Inc. DPU RSC
-
-Snapdragon Display Engine implements display rsc to driver
-display core to different modes for power saving
-
-Required properties
-- compatible:			Must be "qcom,dpu-rsc"
-- reg:				Offset and length of the register set for
-				the device.
-- reg-names:			Names to refer to register sets related
-				to this device
-
-Optional properties:
-- clocks:			List of phandles for clock device nodes
-				needed by the device.
-- clock-names:			List of clock names needed by the device.
-- vdd-supply:			phandle for vdd regulator device node.
-- qcom,dpu-rsc-version:		U32 property represents the rsc version. It helps to
-				select correct sequence for dpu rsc based on version.
-- qcom,dpu-dram-channels:	U32 property represents the number of channels in the
-				Bus memory controller.
-- qcom,dpu-num-nrt-paths:	U32 property represents the number of non-realtime
-				paths in each Bus Scaling Usecase. This value depends on
-				number of AXI ports that are dedicated to non-realtime VBIF
-				for particular chipset.
-				These paths must be defined after rt-paths in
-				"qcom,msm-bus,vectors-KBps" vector request.
-
-Bus Scaling Subnodes:
-- qcom,dpu-data-bus:		Property to provide Bus scaling for data bus access for
-				dpu blocks.
-- qcom,dpu-llcc-bus:		Property to provide Bus scaling for data bus access for
-				mnoc to llcc.
-- qcom,dpu-ebi-bus:		Property to provide Bus scaling for data bus access for
-				llcc to ebi.
-
-Bus Scaling Data:
-- qcom,msm-bus,name:		String property describing client name.
-- qcom,msm-bus,active-only:	Boolean context flag for requests in active or
-				dual (active & sleep) contex
-- qcom,msm-bus,num-cases:	This is the number of Bus Scaling use cases
-				defined in the vectors property.
-- qcom,msm-bus,num-paths:	This represents the number of paths in each
-				Bus Scaling Usecase.
-- qcom,msm-bus,vectors-KBps:	* A series of 4 cell properties, with a format
-				of (src, dst, ab, ib) which is defined at
-				Documentation/devicetree/bindings/arm/msm/msm_bus.txt
-				* Current values of src & dst are defined at
-				include/linux/msm-bus-board.h
