drm/i915/uc: Place uC firmware in upper range of GGTT
Currently we pin the GuC or HuC firmware image just before uploading.
Perma-pin during uC initialization instead and use the range reserved at
the top of the address space.
Moving the firmware resulted in needing to:
- use an additional pinning for the rsa signature which will be used
during HuC auth as addresses above GUC_GGTT_TOP do not map through GTT.
v2: Remove call to set to gtt domain
Do not restore fw gtt mapping unconditionally
Separate out pin/unpin functions and drop usage of pin/unpin
Use uc_fw init/fini functions to bind/unbind fw object
v3: Bind is only needed during xfer (Chris)
Remove attempts to bind outside of xfer (Chris)
Mark fw bind/unbind static
