arm64: dts: renesas: rzt2h-n2h-evk: Remove unused MII/GMII pins

Browse Source 
Remove the unused TXER, RXER, CRS, and COL pinmux configurations from the
gmac1 (ETH3) and gmac2 (ETH2) pin groups.

The Ethernet interfaces on both the RZ/T2H and RZ/N2H EVK boards operate
in RGMII mode, which does not utilize these extra MII/GMII sideband signal
pins. Update the board switch configuration comments to accurately reflect
the pin ranges that are actually in use.
