Subject: [RFC PATCH v2 linux-next 01/14] net: dsa: sja1105: be compatible with "ethernet-ports" OF node name

Since commit f2f3e09396be ("net: dsa: sja1105: be compatible with
"ethernet-ports" OF node name"), DSA supports the "ethernet-ports" name
for the container node of the ports, but the sja1105 driver doesn't,
because it handles some device tree parsing of its own.

Add the second node name as a fallback.
