Adding a i915_fifo_underrun_reset debugfs file will make it possible for IGT tests to clear FIFO underrun fallout at the start of each subtest, and make re-enable FBC so tests always have maximum exposure to features used by IGT. FIFO underruns and FBC bugs will no longer hide when an earlier subtests disables both.
