arm64: dts: mediatek: add ethernet support for mt8365 SoC

This IP is a 10/100 MAC controller compliant with IEEE 802.3 standards.
It supports power management with Energy Efficient Ethernet and Wake-on-LAN
specification. Flow control is provided for half-duplex and full-duplex
mode. For packet transmission and reception, the controller supports
IPv4/UDP/TCP checksum offload and VLAN tag insertion.
