This is a major rework of the old v2 series.

The SoC always support USB 2.0 but for USB 3.0 it needs additional
configuration for the Serdes port. Such port can be either configured
for USB usage or for PCIe lines or HSGMII and these are configured
in the SCU space.

The previous implementation of a dedicated SSR driver was too
complex and fragile for the simple task of configuring a register
hence it was dropped and the handling is entirely in the PHY driver.

Everything was reducted to the dt-bindings to describe the Serdes line.

Also the property for the PHY are renamed to a more suitable name and
everything is now mandatory to simplify the implementation.
(the PHY are always present and active on the SoC)

I get build failure:
