Subject: [PATCH V2 5/9] arm64: dts: renesas: beacon: Cleanup USB References

The programmable versaclock is used for the usb_extal reference clock for
the EHCI driver instead of a fixed-clock.  Because the versaclock needs to
be enabled, the clock reference needs to be added to the clocks list.

For the USB3 Phy, the perferred clock reference is usb3s_clk, so
remove the usb_extal reference.

V2:  Split this off into its own patch.
