It seems a little odd to add this ifdef when it's know that config

understand leaving the ifdef in any other board files that already had
it, but actively adding it here seems strange.

Unrelated change?

Is this actually necessary?

I'll try and test these patches on all the Tegra20 boards I have tomorrow.
