net: phy: genphy: Make it work with of_set_phy_supported 

phys start with features initialized from the phy driver
and are eventually limited by of_set_phy_supported. This
does not work with the genphy driver which starts with
no features and overwrites phydev->supported with the
values read from hardware in config_init. This overwrites
the features adjusted by of_set_phy_supported.
To fix this let the genphy driver start with full features
which are then only limited in config_init, but never
extended.
