net: phy: broadcom: use genphy_c45_an_config_eee_aneg in bcm_config_lre_aneg

bcm_config_lre_aneg() is the only user of genphy_config_eee_advert(),
therefore use genphy_c45_an_config_eee_aneg() instead. The resulting
functionality is equivalent, and bcm_config_lre_aneg() follows the
structure of __genphy_config_aneg().
In a follow-up step genphy_config_eee_advert() can be removed.

Note: We preserve the current behavior to ignore errors.
