The RZ/G2 boards expect there to be an external clock reference for USBHS controller. For the Beacon boards, this reference clock is controlled by a programmable versaclock. Because the RZ/G2 family has a special clock driver when using an external clock, the third clock reference in the USBHS node needs to point to this special clock, called usb2_clksel, and the 4th clock is the versaclock.
