arm64: dts: renesas: beacon: Fix USB ref clock references
The RZ/G2 boards expect there to be an external clock reference for
USB2 EHCI controllers. 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 EHCI node needs to point to this
special clock, called usb2_clksel.
Since the usb2_clksel does not keep the usb_extal clock enabled,
the 4th clock entry for the EHCI nodes needs to reference it to
keep the clock running and make USB functional.
