PATCH v2 1/1 xhci: Add reset on resume quirk for asrock p67 host

The asrock p67 xhci controller completely dies on resume, add a quirk for this, to bring the host back online after a suspend.

This should be backported to stable kernels up until 2.6.37.

No attached patches, just inline ones please. :) I've fixed this up for now, since your first patch was inline.

Actually, it seems I did it both ways by accident. Testing patch -Np1 with that message still worked. Sorry about that. Sent it right before falling asleep.
