These patches add HuC loading support. The GuC is required to
authenticate the HuC. The userspace patches that check for a
fully loaded HuC firmware and use it can be found at:

v2: rebased.
v3: rebased. Changed the code following the review comments.
v4: Added action_lock initialization fix provided by Arek
(Hiler Arkadiusz) to the first patch in the series- Make the
GuC fw loading helper functions general.
v5: rebased on top of drm-tip. The patch series is now in sync with GuC
code reorganization efforts by Arek-
https://patchwork.freedesktop.org/series/15896/
v6: rebased. Organize the code-move contents of intel_huc.h to intel_uc.h. Update functions
intel_huc_load(),intel_huc_init() and intel_uc_fw_fetch() to accept dev_priv instead of dev.
