drm/i915/huc: improve documentation
Better explain the usage of the microcontroller and what i915 is responsible of. While at it, fix the documentation for the auth function, which doesn't do any pinning anymore. v2: add a comment on HuC being optional and descrive how HuC accesses memory (Martin) v3: add extra newline for better text organization (Martin) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Martin Peres <martin.peres@linux.intel.com> Acked-by: Anna Karas <anna.karas@intel.com> Reviewed-by: Martin Peres <martin.peres@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191014183602.3643-3-daniele.ceraolospurio@intel.com
