Subject: [PATCH 3/4] drm/msm/dpu: Add has_data_compress to dpu_caps

Add data_compress feature to DPU HW catalog.

In DPU 7.x and later, there is a DATA_COMPRESS register that must be set
within the DPU INTF block for DSC to work.

As core_rev (and related macros) was removed from the dpu_kms struct, the
most straightforward way to indicate the presence of this register would be
to have a flag in dpu_caps.
