Subject: [PATCH net-next 1/7] net: phy: marvell10g: Use get_features to get the PHY abilities

The Alaska family of 10G PHYs has more abilities than the ones listed in
PHY_10GBIT_FULL_FEATURES, the exact list depending on the model.

Make use of the newly introduced .get_features call to build this list,
using genphy_c45_pma_read_abilities to build the list of supported
linkmodes, and adding autoneg ability based on what's reported by the AN
MMD.

.config_init is still used to validate the interface_mode.
