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.
