drm/amd: Load PSP microcode during early_init

Simplifies the code so that all PSP versions will get the firmware
name from `amdgpu_ucode_ip_version_decode` and then use this filename
to load microcode as part of the early_init process.

Any failures will cause the driver to fail to probe before the firmware

Merge tag 'drm-next-2022-12-13' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
"The biggest highlight is that the accel subsystem framework is merged.
Hopefully for 6.3 we will be able to line up a driver to use it.

In drivers land, i915 enables DG2 support by default now, and nouveau
has a big stability refactoring and initial ampere support, AMD
includes new hw IP support and should build on ARM again. There is
also an ofdrm driver to take over offb on platforms it's used.

Stuff outside my tree, the dma-buf patches hit a few places, the vc4
firmware changes also do, and i915 has some interactions with MEI for
discrete GPUs. I think all of those should have been acked/reviewed by
relevant parties.

UAPI:
- Add new GEM_CREATE flags to help to transition more KFD functionality to the DRM UAPI.
These are used internally in the driver to align location based memory coherency
requirements from memory allocated in the KFD with how we manage GPUVM PTEs. They
are currently blocked in the GEM_CREATE IOCTL as we don't have a user right now.
They are just used internally in the kernel driver for now for existing KFD memory
allocations. So a change to the UAPI header, but no functional change in the UAPI.
