[PATCH v3 0/7] drm/i915/reset: Expose "display_reset_count" in debugfs

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Expose a display reset count in debugfs. It will be used
by kms_busy/*-with-reset tests to confirm they are actually
testing the thing they are meant to test.

This should now pass on all platforms, after the last patch
prevents the per-engine reset shortcut when using execlist
submission.

v2: Deal with the execlist per-engine reset issue
v3: Deal with the stale i915->display floating around in the mock tests
