description:
Tells USB controllers that we want to configure the core to support a
UTMI+ PHY with an 8- or 16-bit interface if UTMI+ is selected, UTMI+ low
pin interface if ULPI is specified, Serial core/PHY interconnect if
serial is specified and High-Speed Inter-Chip feature if HSIC is
selected. In case this isn't passed via DT, USB controllers should
default to HW capability.

Tells USB controllers we want to work up to a certain speed. In case this
