Subject: [PATCH 13/18] arm64: dts: renesas: r9a09g056: Add USB2.0 PHY VBUS internal regulator node
USB2.0 PHY of the RZ/V2N SoC can drive VBUS line via the VBOUT bit of
the VBCTRL register.
Add VBUS regulator nodes (usb2_phy0_vbus_otg) under the usb2_phy0
node to describe this hw functionality.
This enables proper management of VBUS for USB2.0 OTG devices and ensures
compliance with hardware requirements.
