drm/i915/huc: Prepare for GSC-loaded HuC
HuC loading via GSC is performed via a PXP command sent through the mei
modules, so we need both MEI_GSC and MEI_PXP to be available. Given that
the GSC will do both the transfer and the authentication, the legacy HuC
loading paths can be safely skipped.
Also note that the GSC-loaded HuC survives GT reset.
v2: move the huc_is_authenticated() function to this patch.
