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

SM6150 supports MST as far as I can see.

Yes, but since msm_dp_desc hasn't been mainlined with MST enabled yet,
I went ahead and submitted it with this commit message.

The commit message is misleading: it makes one think that SC7180
supports MST, while SM6150 doesn't.
