Subject: [PATCH v2 00/12] drm/msm/dpu: rework format handling code

- Rework mdp_format.c in order to make format table manageable
- Rework layout population for UBWC formats in DPU driver

Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@....qualcomm.com>

Changes in v2:
- Dropped DX flag from the tiled NV12 format structure (Jessica)
- Changed round_up(foo, 192) to the roundup() as the former one is
  supposed to be used with power of 2 argument (Jessica)
- Fixed undefined varuables warning in
  _dpu_format_populate_plane_sizes_ubwc() by dropping the always-true
  condition (LKP)
- Link to v1: https://lore.kernel.org/r/20250705-dpu-formats-v1-0-40f0bb31b8c8@oss.qualcomm.com
