FROMLIST: dt-bindings: display/msm: dp-controller: Add SM6150

Add DisplayPort controller binding for Qualcomm SM6150 SoC.
SM6150 uses the same controller IP as SM8150.
Declare 'qcom,sm6150-dp' as a fallback compatible to
'qcom,sm8150-dp' and 'qcom,sm8350-dp' for consistency with existing
bindings and to ensure correct matching and future clarity.
