drm/i915/uc: consolidate firmware cleanup
We are quite trigger happy in cleaning up the firmware blobs, as we do
so from several error/fini paths in GuC/HuC/uC code. We do have the
__uc_cleanup_firmwares cleanup function, which unwinds
__uc_fetch_firmwares and is already called both from the error path of
gem_init and from gem_driver_release, so let's stop cleaning up from
all the other paths.
The fact that we're not cleaning the firmware immediately means that
we can't consider firmware availability as an indication of
initialization success. A "LOADABLE" status has been added to
indicate that the initialization was successful, to be used to
selectively load HuC only if HuC init has completed (HuC init failure
is not considered a fatal error).
v2: s/ready_to_load/loadable (Michal), only run guc/huc_fini if the
fw is in loadable state
