usb: mtu3: clear SOFTCONN when clear USB3_EN if work as HS mode
When the controller supports SS mode, but works as HS mode, the
SOFTCONN will not be cleared automatically when clear USB3_EN
by default, this cause an issue that can't disconnect from host,
so clear SOFTCONN when clear USB3_EN when the class driver want
to disable the D+ pullup.
