net: dsa: lan9303: imply SMSC_PHY

Both LAN9303 and LAN9354 have internal PHYs on both external ports.
Therefore a configuration without SMSC PHY support is non-practical at
least and leads to:

LAN9303_MDIO 8000f00.mdio:00: Found LAN9303 rev. 1
mdio_bus 8000f00.mdio:00: deferred probe pending: (reason unknown)
