phy: rockchip: inno-usb2: set bvalid to high by grf for rv1103

Browse Source 
RV1103 doesn't have VBUSDET pin for the usb phy to
detect the USB VBUS, and the default status of bvalid
is inactive(low level), it cause the dwc3 controller
fail to start usb device connection, so it needs to
set bvalid to high by grf for RV1103.
