Add complete bindings to instantiate and configure the codec and
top-level audio complex on all currently supported boards using the
Tegra+WM8903 audio driver.

On those boards, disable the I2S2 controller since it isn't used.

On boards not using the WM8903 codec, disable all the audio devices;
they can be re-enabled once the relevant codec and ASoC machine drivers
have been ported to device-tree.

Thinking about that more, I'd like to change this from nvidia,tegra-audio*
to nvidia,tegra20-audio*. That's because the current ASoC machine driver,
which is what matches that compatible flag, is slightly Tegra20-specific
because it makes calls to the Tegra20-specific DAS driver. On Tegra30, this
is replaced by a Tegra30 (and later?) AHUB driver. To avoid the
Tegra+WM8903 ASoC machine driver module depending on both the Tegra20 DAS
module and the Tegra30 AHUB module, I'd like to create separate ASoC
machine drivers for the two Tegra chips, which parameterize a core machine
driver (e.g. by passing an ops/vtable). This requires versioned compatible
flags so that different drivers can be instantiated.
