staging: et131x: Fix errors caused by phydev->addr accesses before initialisation
commit ec0a38bf8b28b036202070cf3ef271e343d9eafc upstream.
Fix two reported bugs, caused by et131x_adapter->phydev->addr being accessed
before it is initialised, by:
- letting et131x_mii_write() take a phydev address, instead of using the one
stored in adapter by default. This is so et131x_mdio_write() can use it's own
addr value.
- removing implementation of et131x_mdio_reset(), as it's not needed.
- moving a call to et131x_disable_phy_coma() in et131x_pci_setup(), which uses
phydev->addr, until after the mdiobus has been registered.

- update more update more et131x_mii_write() calls in
et1310_phy_access_mii_bit() and et131x_xcvr_init()]
