This switches Ventana over to use FDT for run-time config instead of
CONFIG options.

At present Ventana does not have its own device tree file - it just uses
the Seaboard one.

But there's a Ventana-specific tegra-ventana.dts in the kernel...

Have you tested this on Ventana in mainline U-Boot?

Yes, that's right. Perhaps we should drop this patch for now? Ventana
will still build, just not have USB support.
