Subject: [PATCH 1/2] dt-bindings: clock: qcom: document the Glymur GPU
 Clock Controller

Glymur SoC has Qualcomm GX(graphics) clock controller and also the
Graphics clock controller. The GX graphics clock controller helps in the
recovery of the Graphics subsystem.

Add bindings documentation for the Glymur Graphics Clock and Graphics
power domain Controller for Glymur SoC.
