Add pending patches from Alexander 'lynxis' Couzens which are required for RealTek NBase-T PHYs or SFP+ cages to work when connected to the SGMII interface provided by recent MediaTek SoCs [1]. The patches for MT753x fix link speed limitation on CPU ports observed by many users which is due to reset being carried out wrongly [2].
