usb: core: reduce power-on-good delay time of root hub

commit 90d28fb53d4a51299ff324dede015d5cb11b88a2 upstream.

Return the exactly delay time given by root hub descriptor,
this helps to reduce resume time etc.

Due to the root hub descriptor is usually provided by the host
controller driver, if there is compatibility for a root hub,
we can fix it easily without affect other root hub
