riscv: dts: microchip: Add ethernet0 to the aliases node

[ Upstream commit 417166ddec020c4e969aea064e23822591ad54df ]

U-Boot expects this alias to be in place in order to fix up the mac
address of the ethernet node.

Note on the Icicle Kit board, currently only emac1 is enabled so it
becomes the 'ethernet0'.
