riscv: dts: sophgo: cv180x: Fix internal ephy node name

The internal EPHY node is named "phy@0" while its reg property is <1>.
The unit-address should match the first entry of the reg property, but
this is not checked by dtc for MDIO buses. The kernel confirms the PHY
is indeed at address 1:

  eth0: PHY [mdio_mux-0.0:01] driver [Generic PHY]

Rename the node to ethernet-phy@1, which also follows the common naming
convention for ethernet PHY nodes.
