[PATCH 10/15] dt-bindings: display/msm: Document A850 GPU and GMU

[Akhil P Oommen <akhilpo@oss.qualcomm.com>]

Adreno A850 GPU found in Hawi SoC belongs to the A8x family and is
the successor to A840. Like A840, its clocks are described in the GMU
node and it has the following power related updates:
  1. GMU is now powered via a dedicated GDSC connected to MxG rail
  2. An additional power rail called Bx

Describe this GPU/GMU along with the new compatible strings.
