net: tn40xx: prepare tn40xx driver to find phy of the TN9510 card
Prepare the tn40xx driver to load for Tehuti TN9510 cards, which require
bit 3 in the register TN40_REG_MDIO_CMD_STAT to be set. The function of bit
3 is unclear, but may have something to do with the length of the preamble
in the MDIO communication. If bit 3 is not set, the PHY will not be found
when performing a scan for PHYs. Use the available tn40_mdio_set_speed
function which includes setting bit 3. Just move the function to before the
devm_mdio_register function, which scans the mdio bus for PHYs.
