Subject: [PATCH 16/18] arm64: dts: renesas: r9a09g057h44-rzv2h-evk: Enable USB2 PHY0 VBUS support

Enable the vbus-supply and status properties for USB2 PHY0 and its
VBUS OTG regulator in the r9a09g057h44-rzv2h-evk device tree.

Enabling them ensures proper VBUS handling and reliable USB OTG
operation on the channel.
