Re: PCI runtime PM issue on NEC xHCI host

What we've tended to find with other host controllers is that we need to 
force a full reenumeration on resume regardless of whether the hcd 
indicates that there's been any change in port status. Does just adding 
a usb_hcd_resume_root_hub(hcd) at the end of resume fix it? This seems 
better than sleeping for an arbitrary period of time, unless there's any 
magic status bit hidden somewhere.
