[PATCH v2 2/4] dt-bindings: display/msm/gmu: Document RGMU

[Akhil P Oommen]

RGMU a.k.a Reduced Graphics Management Unit is a small state machine
with the sole purpose of providing IFPC support. Compared to GMU, it
doesn't manage GPU clock, voltage scaling, bw voting or any other
functionalities. All it does is detect an idle GPU and toggle the
GDSC switch. So it doesn't require iommu & opp table.
