[PATCH v4 1/4] dt-bindings: display: bridge: Add schema for Synopsys DW HDMI QP TX IP

[Cristian Ciocaltea]

Add dt-binding schema containing the common properties for the Synopsys
DesignWare HDMI QP TX controller.

Note this is not a full dt-binding specification, but is meant to be
referenced by platform-specific bindings for this IP core.
