Backport phylink patches for PCS/PHY caps OPs. This makes it easier to align future generic PCS patch and permit supporting special PHY that needs specific tune if "in-band" mode is enabled (for example Aeonsemi PHYs) This is also mainly using the upstream version of the Mediatek patch 739-net-add-negotiation-of-in-band-capabilities. All affected patch automatically refreshed. Link: https://github.com/openwrt/openwrt/pull/20461 Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
