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

commit 6729188d2646709941903052e4b78e1d82c239b9 upstream.

The driver continues probing when a port is configured for an
unsupported PHY interface type, instead it should stop.

Fixes: 8aa9ebccae87 ("net: dsa: Introduce driver for NXP SJA1105 5-port L2 switch")
