Subject: [PATCH] dt-bindings: usb: amlogic,meson-g12a-usb-ctrl: make G12A
 usb3-phy0 optional

On the G12A USB complex, the USB3 PHY is shared with the PCIe controller,
thus on designs without PCIe enabled the USB3 PHY entry can be ommited from
the PHY list.

Fixes: cdff2c946f06 ("dt-bindings: usb: amlogic,meson-g12a-usb-ctrl: add the Amlogic AXG Families USB Glue Bindings")
