[PATCH v2 net] net: dsa: sja1105: Don't error out on disabled ports with no phy-mode

[Vladimir Oltean]

From: Vladimir Oltean <vladimir.oltean@nxp.com>

The sja1105_parse_ports_node function was tested only on device trees
where all ports were enabled. Fix this check so that the driver
continues to probe only with the ports where status is not "disabled",
as expected.
