From: Michał Winiarski <michal.winiarski@xxxxxxxxx>
The information about platform/driver/user view of GuC firmware usage
currently requires user to either go through kernel log or parse the
combination of "enable_guc" modparam and various debugfs entries.
Let's keep things simple and add a "supported/used/wanted" matrix
(already used internally by i915) in guc_info debugfs.
