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.
