arm64: renesas: Disable AVB1 and AVB2 on R8A779G0 V4H White Hawk board
The U-Boot is currently not capable of handling ethernet-phy-ieee802.3-c45 PHYs correctly, and also does not handle MDIO bus wide reset-gpios property. Until proper C45 PHY support lands in U-Boot, disable AVB1/AVB2 interfaces. This only disables the two MACs with 88Q2110/88Q2112 100/1000BASE-T1 PHYs on ethenet sub-board, the main board AVB0 ethernet is unaffected.
