usb: renesas_usbhs: Use devm_usb_get_phy()

commit e0c92440 upstream.

The gpriv->transceiver is retrieved in probe() through usb_get_phy() but
never released. Use devm_usb_get_phy() to handle this scenario.

This issue was identified through code investigation. No issue was found
without this change.
