i don't know anything about the tegra pinmux details, but the way we setup the
defines in the Blackfin code was to encode all of the bits. thus we didn't need
to switch() on any of the id's, we just unpacked the values at runtime with
bitshifts/masks.

needs ifdef protection against multiple inclusion
