- Move runtime power status info to display power debugfs (Jani)

Refactoring and cleanups:
- Convert i915 and xe to DRM client setup (Thomas)
- Refactor and clean up CDCLK/bw/dbuf readout/sanitation (Ville)
- Conversions from drm_i915_private to struct intel_display (Jani, Suraj)
- Refactor display reset for better separation between display and core (Jani)
- Move panel fitter code together (Jani)
- Add mst and hdcp sub-structs to display structs for clarity (Jani)
- Header refactoring to clarify separation between display and i915 core (Jani)

Fixes:
- Fix DP MST max stream count to match number of pipes (Jani)
- Fix encoder HW state readout of DP MST UHBR (Imre)
- Fix ICL+ combo PHY cursor and coeff polarity programming (Ville)
- Fix pipeDMC and ATS fault handling (Ville)
- Display workarounds (Gustavo)
- Remove duplicate forward declaration (Vinod)
- Improve POWER_DOMAIN_*() macro type safety (Gustavo)
- Move CDCLK post plane programming later (Ville)

DRM core changes:
- Add client-hotplug helper (Thomas)
- Send pending hotplug events after client resume (Thomas)
- Add fb_restore and fb_set_suspend fb helper hooks (Thomas)
- Remove struct fb_probe fb helper hook (Thomas)
- Add const qualifier to drm_atomic_helper_damage_merged() (Vinod)

Xe driver changes:
- Convert i915 and xe to DRM client setup (Thomas)
- Refactor i915 compat headers (Jani)
- Fix fbdev GGTT mapping handling (Maarten)
- Figure out pxp instance from the gem object (Jani)

Merges:
- Backmerge drm-next to fix conflicts with drm-xe-next (Jani)
