>From commit 84b1ca2f0e68 ("drm/i915/uc: prefer intel_gt over i915
in GuC/HuC paths") we stopped using HUC_STATUS error -ENODEV only
to indicate lack of HuC hardware and we started to use this error
also for all other cases when HuC was not in use or supported.

Fix that by relying again on HAS_GT_UC macro, since currently
used function intel_huc_is_supported() is based on HuC firmware
support which could be unsupported also due to force disabled
GuC firmware.
