Subject: [PATCH v2 net-next] net: dsa: sja1105: Avoid error message for unknown PHY mode on disabled ports

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

When sja1105_init_mii_settings iterates over the port list, it prints
this message for disabled ports, because they don't have a valid
phy-mode:

[    4.778702] sja1105 spi2.0: Unsupported PHY mode unknown!
