Initially, this binding and driver only describe/support playback to
headphones and speakers.

This driver will support Beaver and Dalmore.

This adds Kconfig options for the Tegra30 AHUB and I2S controller, and
updates the Tegra+WM8903 machine driver Kconfig to select those.

Rename Tegra20-specific Kconfig variables, module filenames, all internal
symbol names, clocks, and platform devices, to reflect the fact the DAS
and I2S drivers are for a specific HW version.

Rename these files so they include a specific hardware version in their
filenames. The contents is only touched minimally so that git's rename
tracking operates correctly; renaming all symbols in the files results
in a diff so large that the rename detection fails.

The DAS, I2S, and SPDIF drivers are Tegra20-specific. Group these
together so that when Tegra30-specific equivalents are added later, the
file ordering makes sense.

This is mainly for symmetry with a future Tegra30 driver, where the
equivalent of the DAS (the AHUB) is useful separately from the I2S driver.

This is a minimal driver for the Tegra SPDIF controller.

In hardware, the SPDIF output signal is always routed to any active HDMI
display controllers, and may also be routed to external pins on Tegra
using the pinmux.

The previous commit renames SND_TEGRA_SOC_HARMONY to SND_TEGRA_SOC_WM8903.
While we're breaking people's .config files, rename all Tegra/SOC-related
Kconfig variables to be more consistent with at least the core codec
variables. Note that there exist machines that name their variables both
ways.

Soon, this machine driver will be updated to handle a number of Tegra boards
using the WM8903 codec. Rename the file in advance to reflect this.

Fix the content of tegra_wm8903.c to match the rename; replace references
to Harmony board with something more generic.

* s/struct tegra_harmony/struct tegra_wm8903/
* s/harmony/machine/ # variable name
* Similar rename for some functions
* Similar comment fix

The utilities will be required by every machine driver. Including the
utility object directly into every machine driver causes a build failure
if the modules are actually built into the kernel, since each will define
the symbols exported by the utility file. Solve this by moving the
utility object into a separate module.
