Subject: [PATCH 2/2] drm/msm/dpu: remove GC related code from dpu catalog

Since Gamma Correction (GC) block is currently unused, drop
related code from the dpu hardware catalog otherwise this
becomes a burden to carry across chipsets in the catalog.

At this point we can merge these two masks.

Could you please extend this for v2 with the following patches:
- merge of two DSPP_foo_MASKs
- dropping of DPU_DSPP_IGC?

For this patch:
