d37bdf736d ASoC: samsung: Use ASoC dmaengine code where possible
Since all Exynos platforms have been converted to dmaengine and many of
the older platforms are in the process of conversion they do not need to
use the legacy s3c-dma APIs for DMA but can instead use the standard ASoC
dmaengine helpers. This both allows them to benefit from improvements
implemented in the generic code and supports multiplatform.

This patch includes some fixes from Padma for Exynos SoCs, her testing
was on a slightly earlier version of the patch due to unrelated breakage
preventing testing.

3688569e81 ASoC: samsung: Provide helper for DMA init
In preparation for using the dmaengine helpers in ASoC rather than the
dmaengine wrappers for the Samsung API wrap the configuration of dma_data.
The dmaengine code expects different data to that used by the legacy API.

85ff3c29d7 ASoC: samsung: Rename DMA platform registration functions
The current naming with a simple asoc_ prefix is too generic for use in
multiplatform kernels.

a08485d8fd ASoC: Samsung: Do not register samsung audio dma device as pdev
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 change removes the platform_device completely. Each Samsung DAI now
registers the ASoC 'platform' itself. Machine drivers are adjusted for
the new 'platform' name.

344b4c4888 ASoC: Samsung: Update DMA interface
This patch adds to support the DMA PL330 driver that uses
DMA generic API. Samsung sound driver uses DMA generic API
if architecture supports it. Otherwise, use samsung specific
S3C-PL330 API driver to transfer PCM data.

This patch moves DMA specific definitions, they doesn't need to be
shared, into 'dma.c' from 'dma.h'. And remove unnecessery definitions
on 'dma.h'.
