drm: add msm compressed format modifiers 

Qualcomm Snapdragon chipsets uses compressed format
to optimize BW across multiple IP's. This change adds
needed modifier support in drm for a simple 4x4 tile
based compressed variants of base formats.

Changes in v3:
- Removed duplicate entry for DRM_FORMAT_MOD_QCOM_COMPRESSED (Rob Clark)
Changes in v4:
- Remove all modifiers aside from COMPRESSED, this includes tiled and
  10-bit
