The firmware will send the context reset notification message as
part of handling hardware recovery (HWR) events deecoding the message
and printing via drm_info(). This eliminates the "Unknown FWCCB command"

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.

drm/imagination: Add RISC-V firmware processor support

Newer PowerVR GPUs (such as the BXS-4-64 MC1) use a RISC-V firmware
processor instead of the previous MIPS or META.

The current version of this patch depends on a patch[1] which exists in
drm-misc-fixes, but has not yet made it back to drm-misc-next (the
target of this patch). That patch adds the function pvr_vm_unmap_obj()
which is used here.
