riscv: dts: thead: Add TH1520 ethernet nodes 



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

Signed-off-by: default avatarEmil Renner Berthing <emil.renner.berthing@canonical.com>
[drew: change apb registers from syscon to second reg of gmac node,
       add phy reset delay properties for beaglev ahead]
