[PATCH V2 1/2] ARM: dts: rmobile: beacon-renesom: Enable USB and ethernet ref clocks
There are two versaclock programmable clock chips used to provide reference clocks for both USB and Ethernet. Enable the driver in the configs to run these clocks.

Now that the versaclock driver is available, point the ethernet node at these clocks and configure the RGMII to enable Ethernet.

Go ahead and drop this now. I have FIT working with multiple DTB's from one config file. I'll push a new series to unify M/N/H boards into one defconfig, then add new the functions to the one remaining board. That should eliminate a lot of duplicated entries.
