Pull drm updates from Dave Airlie:
"The usual lots of work all over the place.
i915 has gotten some Alderlake work and prelim DG1 code, along with a
major locking rework over the GEM code, and brings back the property
of timing out long running jobs using a watchdog. amdgpu has some
Alderbran support (new GPU), freesync HDMI support along with a lot
other fixes.
Outside of the drm, there is a new printf specifier added which should
have all the correct acks/sobs:
- printk fourcc modifier support added %p4cc
