[PATCH v2 2/2] riscv: dts: sophgo: add Milk-V Duo ethernet DTB

[Hiago De Franco]

Add a DTB that applies the shared cv18xx-eth.dtbo overlay to the Milk-V
Duo (CV1800B) base DTB. This enables gmac0 and the internal PHY MDIO mux
on boards with the Ethernet IO board, matching the existing Milk-V Duo
256M DTB.
