[PATCH V2 1/2] ARM: dts: rmobile: beacon-renesom: Enable USB and ethernet ref clocks

[Adam Ford]

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.

[PATCH V2 2/2] ARM: dts: rmobile: beacon-renesom: Enable Ethernet

[Adam Ford]

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.
