dt-bindings: phy: renesas,usb2-phy: Document mux-states property
Some Renesas SoCs, such as RZ/G3E, provide a USB2.0 OTG PHY with
configurable VBUS control through a multiplexed hardware register.
This register allows selecting the VBUS source via a mux control
line exposed by the PHY.
To represent this hardware configuration, support the standard
`mux-states` property in the Renesas USB2 PHY binding.
This allows the DeviceTree to model the VBUS source selection as
a mux, consistent with generic binding conventions.
