drm/msm/dpu: Set DATA_COMPRESS on command mode for DCE/DSC 1.2
Add a DPU INTF op to set the DCE_DATA_COMPRESS bit to enable the DCE/DSC 1.2 datapath Note: For now, this op is called for command mode encoders only. Changes to set DATA_COMPRESS for video mode encoders will be posted along with DSC v1.2 support for DP.
