With GuC v9, new type of Default/critical logging in GuC to enable
capturing minimal important logs in production systems efficiently.
This patch enables this logging in GuC by default always. It should
be noted that streaming support with half-full interrupt mechanism
that is present for normal logging is not present for this type of
logging.
v2: Emulated GuC critical logging through i915.guc_log_level.
v3: Commit message update. Enable default/critical logging in GuC always.
Fixed RPM wake during guc_log_unregister in the unload path.
v4: Moved RPM wake change to separate patch. Removed GUC_DEBUG_RESERVED
and updated name of new bit to be version agnostic. Updated parameter to
struct intel_guc * and name of macro NEEDS_GUC_CRITICAL_LOGGING.
Removed explicit clearing of GUC_CRITICAL_LOGGING_DISABLED from
params[GUC_CTL_DEBUG] as it is unnecessary. (Michal Wajdeczko)
v5: Removed GUC_CRITICAL_LOGGING_DISABLED. Added HAS_GUC check to
GUC_NEEDS_CRITICAL_LOGGING. (Michal Wajdeczko)
v6: More refined version of GUC_NEEDS_CRITICAL_LOGGING. Commit message
update. (Michal Wajdeczko)
