Log:
Fix problem with suspend and resume when using Skylake chipsets. Make
sure the XHCI controller is reset after halting it. The problem is
clearly a BIOS bug as the suspend and resume is failing without
loading the XHCI driver. The same happens when using Linux and the
XHCI driver is not loaded.
