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.

Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a
platform_device. This didn't represent the hardware well, since there
was no separate hardware associated with this platform_device; it was a
virtual device with sole purpose to call snd_soc_register_platform().
This mechanism required all board files to register this device, and all
ASoC machine drivers to create and register this device when booting
using device tree.
This change removes the platform_device completely. Each Tegra DAI now
registers the ASoC 'platform' itself. Machine drivers are adjusted for
the new 'platform' name.

Missed .owner of struct snd_soc_card will prevent the module from being

Move DAS routing setup into the DAS driver itself. This removes the need
to duplicate this in each machine driver, of which we'll soon have three.
An added advantage is that the machine drivers no longer call the Tegra20-
specific DAS functions by name, so the machine driver no longer needs to
be split up into Tegra20 and Tegra30 versions.
If individual machine drivers need a different routing setup to this
default, they can still call the DAS functions to set that up.
Long-term, DAS will be a codec driver, and user-space will be able to
control its routing, possibly within constraints that the machine driver
sets up. Configuring the DAS routing from the DAS driver is a very slight
move in that direction.

Set card.fully_routed to request the ASoC core calculated unused codec
pins, and call snd_soc_dapm_nc_pin() for them. Remove the open-coded
calls.

module_platform_driver saves some boiler-plate code.
The devm_ APIs remove the need to manually clean up allocations,
thus removing some code.

This removes potentially machine-specific routing knowledge from the
I2S driverinto the machine drivers, which is better equipped to know
what the appropriate routing configuration is.

The core will sync DAPM as part of the card initialization, there is no
need for machine drivers to do so during their setup.
OMAP drivers are omitted as I know Peter already has patches for them.
