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

Git-commit: 37fe45ad126dd5e9ade8be7ae5010fa1072abbbc
Patch-mainline: v5.6-rc1
References: jsc#SLE-9263

The felix_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.
