staging: et131x: Fix errors caused by phydev->addr accesses before initialisation

Browse source

commit ec0a38bf8b 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.
