T-HEAD Devicetrees for v6.13, part 2

Add gmac, mdio, and phy nodes to enable the gigabit Ethernet ports on
the TH1520 SoC-based BeagleV Ahead and Sipeed Lichee Pi 4a boards.

The dwmac-thead driver and dt binding have been accepted by netdev and
are in linux-next as well as the dts patch in this pull request. I have
tested next-20241108 on the Ahead and LPi4a boards, and Ethernet works
correctly.
