xhci: use default USB_RESUME_TIMEOUT when resuming ports.
USB2 host inititated resume, and system suspend bus resume
need to use the same USB_RESUME_TIMEOUT as elsewhere.
This resolves a device disconnect issue at system resume seen
on Intel Braswell and Apollolake, but is in no way limited to
those platforms.
