[Intel-gfx] [PATCH 2/6] drm/i915/guc: Print status register when waiting for GuC to load

From: John Harrison <John.C.Harrison at Intel.com>

If the GuC load is taking an excessively long time, the wait loop
currently prints the GT frequency. Extend that to include the GuC
status as well so we can see if the GuC is actually making progress or
not.
