MLK-13638-6 usb: chipidea: add recovery from vbus is off during system suspend

When the vbus is off during the suspend controller is powered off, if we
do not want to see disconnection from USB core, we need to make sure the
device pulls DP up before USB core resume runs. However, several devices
are slow to pull DP up when see vbus (maybe it needs vbus to power up
system), so we need to wait connection at platform code.
