Note that whatever option is chosen the configuration should be pulled
in at runtime, it's purely a question of where the data table goes - do
you pass the full thing through platform datra or do you just pass the
machine type.

Another thing to bear in mind is that it's only feasable to try to
combine the Tegra/WM8903 combinations - trying to combine machine
drivers for multiple unrelated CODECs isn't going to work well.
