[Intel-gfx] [PATCH v4 3/5] drm/i915/guc: symbolic name for GuC log-level none

[Dave Gordon]

The existing code that accesses the "guc_log_level" parameter
uses an explicit numerical value for the "no logging" case,
whereas there are symbolic names for the other levels.

So this patch just provides and uses a name for the default log
level (NONE), with the same numeric value that is already used.

This should produce identical code to the previous version!
