xhci: Regression fix for 3.13

Hi Greg,

In 3.12-rc5, I merged a patch that was supposed to fix spurious reboots on
shutdown on HP systems.  The quirk was broadly applied to all Intel Haswell and
Haswell ULT systems.  Turns out the quirk caused non-HP systems to reboot on
suspend.  They shutdown just fine with the quirk patch reverted.  This patch
narrows the xHCI quirk to only run on HP systems.

Sometimes fixing firmware issues feels like plugging holes in a leaky boat.
