Pull drm updates from Dave Airlie:
 "As part of building up nova-core/nova-drm pieces we've brought in some
  rust abstractions through this tree, aux bus being the main one, with
  devres changes also in the driver-core tree. Along with the drm core
  abstractions and enough nova-core/nova-drm to use them. This is still
  all stub work under construction, to build the nova driver upstream.

  The other big NVIDIA related one is nouveau adds support for
  Hopper/Blackwell GPUs, this required a new GSP firmware update to
  570.144, and a bunch of rework in order to support multiple fw
  interfaces.

  There is also the introduction of an asahi uapi header file as a
  precursor to getting the real driver in later, but to unblock
  userspace mesa packages while the driver is trapped behind rust
  enablement.

  Otherwise it's the usual mixture of stuff all over, amdgpu, i915/xe,
  and msm being the main ones, and some changes to vsprintf.

  new drivers:
   - bring in the asahi uapi header standalone
   - nova-drm: stub driver

  rust dependencies (for nova-core):
   - auxiliary
       - bus abstractions
       - driver registration

   - DP powerup/down link helpers
   - extended %p4cc in vsprintf.c to support fourcc prints
   - change vsprintf %p4cn to %p4chR, remove %p4cn
   - Add drm_file_err function
   - IN_FORMATS_ASYNC property
   - move sitronix from tiny to their own subdir
