Johan Hovold 27df5bca96 xhci: fix debugfs register accesses while suspended 
commit 735baf1b23 upstream.

Wire up the debugfs regset device pointer so that the controller is
resumed before accessing registers to avoid crashing or locking up if it
happens to be runtime suspended.

Fixes: 02b6fdc2a1 ("usb: xhci: Add debugfs interface for xHCI driver")
