usb: xhci: Fix problem with xhci resume from suspend 



I have a ASUS PN51 S mini pc that has two xhci devices. One from AMD,
and other from ASMEDIA. The one from ASMEDIA have problems when resume
from suspend, and keep broken until unplug the  power cord. I use this
kernel parameter: xhci-hcd.quirks=128 and then it works ok. I make a
path to reset only the ASMEDIA xhci.
