MLK-13308-2 usb: phy: phy-mxs-usb: handle USB PHY event

For mxs PHY, if there is a vbus but the bus is not enumerated,
force the dp/dm as SE0 from the consider side. If not, there
is possible USB wakeup due to unstable dp/dm, since there is
possible no pull on dp/dm, eg, there is a USB charger on the
port. Note, the vbus event is only occurred at device mode,
and sent by udc driver.
