Well, I think there will be one more; we're hoping to start uptreaming Tegra30
support soon, and the reference board for that will be Cardhu. That'll likely
happen before we have the initialize-pinmux-from-device-tree patches complete,
since I'm holding those off until we all think about whether the new pinmux API
core should be driving the initialization rather than individual pinmux drivers.

But, I hope Ventana and Cardhu will be the last before that's in place.

If not, we can certainly switch these if's to a table.
