Subject: [PATCH v5 1/3] dt-bindings: display/msm: Add SM6150 DisplayPort
 controller

From: Xiangxu Yin <xiangxu.yin@....qualcomm.com>

SM6150 uses the same DisplayPort controller as SM8150, which is already
compatible with SM8350. Add the SM6150-specific compatible string and
update the binding example accordingly.
