Subject: [PATCH v5 2/5] dt-bindings: display/msm: dp-controller: document
 QCS8300 compatible

Add compatible string for the DisplayPort controller found on the
Qualcomm QCS8300 SoC, which uses the same DPU as the SA8775P. While
DP0 supports 4 MST streams, DP1 has been removed at the silicon level,
so SA8775P/SM8650 cannot be used as fallback compatibles.
