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.
