[PATCH 1/2] net: ethernet: adi: bfin_mac: use phydev from struct net_device

[Philippe Reynes]

The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phydev in the private structure, and update the driver to use the
one contained in struct net_device.

[PATCH 2/2] net: ethernet: adi: bfin_mac: use phy_ethtool_{get|set}_link_ksettings

[Philippe Reynes]

There are two generics functions phy_ethtool_{get|set}_link_ksettings,
so we can use them instead of defining the same code in the driver.

There was a check on CAP_NET_ADMIN in bfin_mac_ethtool_setsettings,
but this check is already done in dev_ethtool, so no need to repeat
it before calling the generic function.
