net: fec_mxc: fix usage of DM_MDIO and DM_ETH_PHY

If DM_ETH_PHY is used and the FEC instance owns the shared MDIO bus,
eth_phy_get_mdio_bus returns NULL. If DM_MDIO bus is used, the
mdio_register API is called from dm_mdio_post_probe. Therefore the
bus should must be queried by name in this case.

For DM_MDIO case fec_mii_setspeed has already being called in
dm_fec_mdio_probe(), so skip setting this again.

Fixes: 3b8f99a3e762 ("net: fec: add support for DM_MDIO")
Fixes: e75d08821574 ("net: fec-mxc: prevent crash if no MAC address is set")
