[PATCH 1/3] net: airoha: probe airoha switch mdio on airoha_eth probing

[Mikhail Kshevetskiy]

Airoha switch mdio maybe used not only by GDM1, but also by other GDM
ports (ex: as21xxx phy connected to GDM2 port). So it's better probe
airoha switch mdio a bit early in the airoha_eth_probe() code.

Also remove useless eth_phy_set_mdio_bus() call and related code.
