[PATCH net-next] phy: lan966x: add support for QUSGMII

[Maxime Chevallier <maxime.chevallier@bootlin.com>]

Makes so that the serdes driver also takes QUSGMII in consideration.
It's configured exactly as QSGMII as far as the serdes driver is
concerned.

Dear netdev and Generic PHY maintainers,

This patch should go through the net-next tree instead of the generic
PHY tree, as it has a dependency on :

5e61fe157a27 "net: phy: Introduce QUSGMII PHY mode"

This commits only lives in the net-next tree as of today.

Given the simplicity of this patch, would that be OK for you ?

Thanks,

Maxime
