net: stmmac: remove pcs_get_adv_lp() support
It appears that the GMAC_ANE_ADV and GMAC_ANE_LPA registers are only
available for TBI and RTBI PHY interfaces. In commit 482b3c3ba757
("net: stmmac: Drop TBI/RTBI PCS flags") support for these was dropped,
and thus it no longer makes sense to access these registers.
Remove the *_get_adv_lp() functions, and the now redundant struct
rgmii_adv and STMMAC_PCS_* definitions.
