Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

If the dismod is specified in the DT node, use the specified custom value
to configure the drive on state of the inactive TX slots.
If the dismod is not present or booted in legacy mode, the dismod is set
to low as it was the original behavior.

Rename the struct for the platform data:
snd_platform_data -> davinci_mcasp_pdata
Since we have users under arch/arm/mach-davinci/ for this struct add
temporary define to avoid breakage. The arch code can be updated later to
use the new struct name.

The IP in DRA7xx is similar to the IP found in TI81xxAM3xxx/AM4xxx type of
SoCs but it is is integrated with sDMA instead of eDMA. The suitable pcm
driver for DRA7xx is the omap-pcm driver which is using dmaengine.
In the driver we can configure both dma related structures used for eDMA and
sDMA. The only thing we need to make sure that we set the correct dma_data
at startup with snd_soc_dai_set_dma_data()

Extract DMA channels directly from DT as they can not be found from
platform resources anymore. This is a work-around until davinci audio
driver is updated to use dmaengine.

codec_fmt and sample_rate variables are unused in both snd_platform_data
and davinci_audio_dev, so drop them.

Removes the DaVinci private SRAM API and replaces it with
the genalloc API. The SRAM gen_pool is passed in pdata since
DaVinci is in the early stages of DT conversion.
[[email protected]: stub out gen_pool functions for
!CONFIG_GENERIC_ALLOCATOR]

The OMAP2+ variant of McASP is different from Davinci variant w.r.to
some register offset.
Changes
- Add new MCASP_VERSION_3 to identify new variant. New DT compatible
"ti,omap2-mcasp-audio" to identify version 3 controller.
- The register offsets are handled depending on the version.
Note:
DMA parameters (dma fifo offset) are not updated and will be done later.

Davinci McASP header & driver are shared by few OMAP platforms (like
TI81xx, AM335x). Splitting asp header into Davinci platform specific
header and Audio specific header helps to share them across platforms.
Audio specific defines is moved to to common
<linux/platform_data/davinci_asp.h> so that the header can be
accessed by all related platforms.
While here, correct the header usage (remove multiple header
re-definitions and unused headers) and remove platform names from
structures comments and enum. Also some some coding style errors.
