Subject: [PATCH 4/4] drm/msm/dpu: remove DSC feature bit for PINGPONG on
 SDM630

The MSM8937 platform doesn't have DSC blocks nor does have it DSC
registers in the PINGPONG block. Drop the DPU_PINGPONG_DSC feature bit
from the PINGPONG's feature mask, replacing PINGPONG_SDM845_MASK and
PINGPONG_SDM845_TE2_MASK with proper bitmasks.

Fixes: 7204df5e7e68 ("drm/msm/dpu: add support for SDM660 and SDM630 platforms")
