net: tsec: convert to use DM_MDIO when DM_ETH enabled

Browse source 
For the platforms on which the eTSEC driver uses DM_ETH, convert its
MDIO controller code to also use DM_MDIO.

Note that for handling the TBI PHY (the MAC PCS for SGMII), we still
don't register a udevice for it, since we can drive it locally and there
is no point in doing otherwise.
