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

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

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.

Fixes: bdeced75b13f ("net: dsa: felix: Add PCS operations for PHYLINK")
Signed-off-by: Vladimir Oltean <vladimir.oltean@....com>

Changes in v2:
- Use for_each_available_child_of_node instead of open-coding the
  of_device_is_available check.
