This is a resend of the V4 of a previous series [1] initially aimed at introducing inband extensions, with modes like QUSGMII. This mode allows passing info in the ethernet preamble between the MAC and the PHY, such as timestamps. This series has now become a preliminary series, that simply introduces the new interface mode, without support for inband extensions, that will come later. The reasonning is that work will need to be done in the networking subsystem, but also in the generic phy driver subsystem to allow serdes configuration for qusgmii. This series add the mode, the relevant binding changes, adds support for it in the lan966x driver, and also introduces a small helper to get the number of links a given phy mode can carry (think 1 for SGMII and 4 for QSGMII). This allows for better readability and will prove useful when (if) we support PSGMII (5 links on 1 interface) and OUSGMII (8 links on one interface). V4 contains no change but the collected Reviewed-by from Andrew.
