drm/i915/guc: improve documentation
Add a short description of what we expect from GuC and some minor improvements to existing documentation. Also remove a comment about a difference between GuC and HuC that is not true anymore. v2: add that the GuC is not mandatory (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: Matthew Brost <matthew.brost@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/20191014183602.3643-2-daniele.ceraolospurio@intel.com
