Merge branches 'msm-next-lumag-core', 'msm-next-lumag-dpu', 'msm-next-lumag-dp', 'msm-next-lumag-dsi', 'msm-next-lumag-hdmi', 'msm-next-lumag-mdp5' and 'msm-next-lumag-mdp4' into msm-next-lumag

Changes in this merge:
Core:
- client utilization via fdinfo support
- fix fence rollover issue

DPU:
- constification of HW catalog
- support for using encoder as CRC source
- WB support on sc7180
- WB resolution fixes
- enable DSPP support for sc7280

DP:
- dropped custom bulk clock implementation
- made dp_bridge_mode_valid() return MODE_CLOCK_HIGH where applicable
- fix link retraining on resolution change

MDP5:
- MSM8953 perf data

HDMI:
- YAML'ification of schema
- dropped obsolete GPIO support
- misc cleanups
