Jordan Crouse a168b512de dt-bindings: display: msm: Convert GMU bindings to YAML
Convert display/msm/gmu.txt to display/msm/gmu.yaml and remove the old
text bindings.  The 'sram' text from the old binding never applied to
the GMU so it was not converted but all the other properties were correct.

title: Devicetree bindings for the GMU attached to certain Adreno GPUs
maintainers:
- Rob Clark <robdclark@gmail.com>
description: |
These bindings describe the Graphics Management Unit (GMU) that is attached
to members of the Adreno A6xx GPU family. The GMU provides on-device power
management and support to improve power efficiency and reduce the load on
the CPU.
