[PATCH 1/7] drm/i915: Update i915.reset to handle engine resets

[Matthew Auld]

From: "arun.siluvery at linux.intel.com" <arun.siluvery at linux.intel.com>

In preparation for engine reset work update this parameter to handle more
than one type of reset. Default at the moment is still full gpu reset.
