Revert "usb: host: skip xHCI power management upon port suspend" 



This reverts commit commit 40041445 ("usb: host: skip xHCI power
management upon port suspend"). The host controller does need to clear
run/stop bit upon suspend and set it upon resume in order to properly
support controller entering/exiting low power mode.
