When changing the default values for guc_log_level, we accidentally left
the log enabled on non-guc platforms. Let's fix that.
v2: Define the levels used and remove (now obsolete) comments (Chris)
v3: Use "IS" rather than "TO" for booleans (Chris)
Fixes: 9605d1ce7c6b ("drm/i915/guc: Default to non-verbose GuC logging")
