Pull drm fixes from Dave Airlie:
 "Regular fixes for the week to end the merge window, i915 and xe have a
  few each, amdgpu makes up most of it with a bunch of SR-IOV related
  fixes amongst others.

  i915:
   - Fix BMG support to UHBR13.5
   - Two PSR fixes
   - Fix colorimetry detection for DP

  xe:
   - Fix macro for checking minimum GuC version
   - Fix CCS offset calculation for some BMG SKUs
   - Fix locking on memory usage reporting via fdinfo and BO destroy
   - Fix GPU page fault handler on a closed VM
   - Fix overflow in oa batch buffer

  amdgpu:
   - MES 12 fix
   - KFD fence sync fix
   - SR-IOV fixes
   - VCN 4.0.6 fix
   - SDMA 7.x fix
   - Bump driver version to note cleared VRAM support
   - SWSMU fix
   - CU occupancy logic fix
   - SDMA queue fix"
