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

BugLink: https://bugs.launchpad.net/bugs/1862429
[ Upstream commit 27afe0d34e9121a3d61cc0af9b17c2542dadde24 ]

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.
