This driver is parameterized in two ways:
a) Platform data, which supplies a set of GPIOs used by the driver. These GPIOs can now be parsed out of device tree.
b) Machine-specific DAPM route arrays embedded into the ASoC machine driver itself. The driver picks the appropriate array to use using machine_is_*(). This array can now be parsed straight out of device tree, allowing the machine driver to be completely machine agnostic.
swarren applied the following modifications:
- Moved all pdata and DT parsing into one place.
- Added DAPM route parsing from DT.
- Added tegra_pcm device registration.
- Documented DT binding.

Minor nit: perhaps this should use memcpy() instead?
