Subject: [PATCH v2 2/2] riscv: dts: microchip: Add ethernet0 to the aliases node

From: Bin Meng <bin.meng@...driver.com>

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'.

Signed-off-by: Bin Meng <bin.meng@...driver.com>

Changes in v2:
- move the aliases node to board dts
