[Intel-gfx] [PATCH 5/5] drm/i915: Include RPS threshold in error state

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Now that we allow them to be modified, lets include them in the error
state so it is visible when they have been modified in GPU hang triage.
