arm64: dts: renesas: rzg2ul: Set Ethernet PVDD to 1.8V

Browse Source 
On the RZ/G2UL & RZ/Five SMARC SOMs, the RGMII interface between the SoC
and the Ethernet PHY operates at 1.8V.

The power supply for this interface may be correctly configured in
u-boot, but the kernel should not be relying on this. Now that the
RZ/G2L pinctrl driver supports configuring the Ethernet power supply
voltage, we can simply specify the desired voltage in the device tree.
