[PATCH 11/17] ASoC: tegra: complete Tegra->Tegra20 renaming

[Stephen Warren <swarren@xxxxxxxxxxxxx>]

From: Stephen Warren <swarren@xxxxxxxxxx>

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.

Signed-off-by: Stephen Warren <swarren@xxxxxxxxxx>
