Subject: [PATCH net-next] net: enetc: Support ethernet aliases in dts.

Retrieve the "ethernet" alias ID from the DTS and assign it as the
interface name (e.g., "eth0", "eth1"). This ensures predictable naming
aligned with the DTS's configuration.

If no alias is defined, fall back to the kernel's default enumeration
to maintain backward compatibility.
