I have chosen to copy the whole pinmux data to each leaf .dts even if they are very similar because it will be easier that way to check in the future that they match the canonical data in tegra-pinmux-scripts.

ChromeOS uses one config for both.  The only audio difference between
these two boards is the speakers, that isn't represented in UCM, so
one config file is fine.
