Subject: [PATCH net-next v2 1/4] net: phy: simplify genphy_config_advert by
 using the linkmode_adv_to_xxx_t functions

Using linkmode_adv_to_mii_adv_t and linkmode_adv_to_mii_ctrl1000_t
allows to simplify the code. In addition avoiding the conversion to
the legacy u32 advertisement format allows to remove the warning.
