Enable the USB3.0 (CH0) and USB3.1 (CH1) host controllers on the RZ/V2H
Evaluation Kit. The CN4 stacked connector on the EVK provides access to
both channels, with CH0 corresponding to USB3.0 and CH1 to USB3.1.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
