Subject: [PATCH] net: netcp: Fix ethss driver probe issue

Recent commit below has introduced a bug in netcp driver that causes
the ethss driver probe failure and thus break the networking function
on K2 SoCs such as K2HK, K2L, K2E etc. This patch fixes the issue to
restore networking on the above SoCs.

Fixes: 21c328dcecfc ("net: ethernet: Convert to using %pOFn instead of device_node.name")
