net: phy: Fix verification of EEE support in phy_init_eee

phy_init_eee uses phy_find_setting(phydev->speed, phydev->duplex)
to find a valid entry in the settings array for the given speed
and duplex value. For full duplex 1000baseT, this will return
the first matching entry, which is the entry for 1000baseKX_Full.

If the phy eee does not support 1000baseKX_Full, this entry will not
match, causing phy_init_eee to fail for no good reason.

Fixes: 9a9c56cb34e6 ("net: phy: fix a bug when verify the EEE support")
Fixes: 3e7077067e80c ("phy: Expand phy speed/duplex settings array")
