According to the hardware documentation, GDRST is exactly the same as on
Sandybridge.  So simply enable the existing code.

GPU reset does not seem terribly reliable, but did work at least once:

My GPU hung halfway through an OpenArena run, successfully reset (the screen
went blank for a moment), and continued rendering, finishing the time demo.

I was also able to run glxgears after the reset.
