drm/i915/selftests: Add tests for GT and engine workaround verification Two simple selftests which test that both GT and engine workarounds are not lost after either a full GPU reset, or after the per-engine ones. (Including checks that one engine reset is not affecting workarounds not belonging to itself.) v2: * Rebase for series refactoring. * Add spinner for actual engine reset! * Add idle reset test as well. (Chris Wilson) * Share existing global_reset_lock. (Chris Wilson) v3: * intel_engine_verify_workarounds can be static. * API rename. (Chris Wilson) * Move global reset lock out of the loop. (Chris Wilson) v4: * Add missing rpm puts.

drm/i915/selftests: Split igt_atomic_reset testcase Split igt_atomic_reset selftests into separate full & engines parts, so we can move former to the dedicated reset selftests file. While here change engines test to loop first over atomic phases and then loop over available engines.
