usb: phy: phy-gpio-vbus-usb: Add device tree probing
Make it possible to probe the GPIO VBUS detection driver
from the device tree compatible for GPIO USB B connectors.
Since this driver is using the "gpio-usb-b-connector"
compatible, it is important to discern it from the role
switch connector driver (which does not provide a phy),
so we add some Kconfig text and depend on !USB_CONN_GPIO.
