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.
