Dave Airlie c815e4e79b Merge tag 'drm-msm-next-2024-05-07' of https://gitlab.freedesktop.org/drm/msm into drm-next 
Updates for v6.10

Core:
- Switched to generating register header files during build process
  instead of shipping pre-generated headers
- Merged DPU and MDP4 format databases.

DP:
- Stop using compat string to distinguish DP and eDP cases
- Added support for X Elite platform (X1E80100)
- Reworked DP aux/audio support
- Added SM6350 DP to the bindings (no driver changes, using SM8350
  as a fallback compat)

GPU:
- a7xx perfcntr reg fixes
- MAINTAINERS updates
- a750 devcoredump support
