The other place where this information is interesting is in
i915_gpu_error.c

Can we take a copy of struct intel_uc_fw for huc/guc and pretty print
it? Would require us to expose some methods for drm_printer to redirect
it back to the error_state_buf. On paper it seems feasible.

In the back of my mind, I would like to get similar reuse for
intel_engine_dump and error-state. That seems a bit trickier as we have
to make copies of more things (whereas here we just take a shallow copy
of the struct uc_fw).
