pinctrl: renesas: rzg2l: Limit 2.5V power supply to Ethernet interfaces



The RZ/G3S SoC supports configurable supply voltages for several of its
I/O interfaces. All of these interfaces support both 1.8V and 3.3V
supplies, but only the Ethernet and XSPI interfaces support a 2.5V
supply.

Voltage selection for the XSPI interface is not yet supported, so this
leaves only the Ethernet interfaces currently supporting selection of a
2.5V supply. So we need to return an error if there is an attempt to
select a 2.5V supply for any non-Ethernet interface.
