[Intel-xe] [PATCH 0/2] HuC authentication via GSC

[Daniele Ceraolo Spurio]

Starting on MTL, in addition to the authentication via GuC, we need to
perform a second HuC authentication via GSC. This second authentication
is required to allow the HuC to process protected content and is
performed by sending a dedicated PXP command to the GSC firmware.
