This is only necessary at present since the devicetree support relies on
some aspects of some existing hard-coded board file for some parts of
initialization. In the long run, that code can be ported to devicetree
too.

I needed to test devicetree support on Tegra Seaboard rather than Harmony.
This patch is the changes I needed to make to have that work. It builds on
the previous patches I recently posted. It's only an FYI just in case
anyone else finds it useful.
