[PATCH] net: dsa: ar9331: Publish the OF module alias

The AR9331 switch driver registers an OF match table on the MDIO bus.
The bus emits an OF modalias for matching devices, but this table is
not exported to the module's alias metadata.

Publish the existing table without changing DSA registration or routing.

Fixes: ec6698c272de ("net: dsa: add support for Atheros AR9331 built-in switch")
