From: Arun Siluvery <arun.siluv...@linux.intel.com>
A new variable is added to export the reset counts to debugfs, this
includes full gpu reset and engine reset count. This is useful for tests
where they are expected to trigger reset; these counts are checked before
and after the test to ensure the same.
