ASoC: Tegra: Support more boards

* Ventana is identical to Harmony.
* Seaboard, Kaen, and Aebl are all pretty similar, mainly with slightly
  different sets of GPIOs, and slightly different WM8903 pin connectivity.

Say Y or M here if you want to add support for SoC audio on Tegra
boards using the WM8093 codec. Currently, the only supported board
is Harmony.
