Subject: [PATCH v3 13/14] drm/msm/dp: Add DisplayPort support for sm6150

Add support for SM6150 DisplayPort controller, which shares base offset
and configuration with SC7180. While SM6150 lacks some SC7180 features
(e.g. HBR3), current msm_dp_desc_sc7180 data is sufficient. Listing it
explicitly ensures future compatibility.
