ASoC: ti: davinci-i2s: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

ASoC: ti: Migrate to new style legacy DAI naming flag
Change the legacy DAI naming flag from opting in to the new scheme
(non_legacy_dai_naming), to opting out of it (legacy_dai_naming).
These drivers appear to be on the CPU side of the DAI link and
currently uses the legacy naming, so add the new flag.

ASoC: ti: Rename set_fmt_new back to set_fmt
Now the core has been migrated across to the new direct clock
specification we can move the drivers back to the normal set_fmt
callback.

ASoC: ti: Update to use set_fmt_new callback

ASoC: ti: davinci-i2s: Add check for clk_enable()
As the potential failure of the clk_enable(),
it should be better to check it and return error
if fails.

ASoC: ti: davinci-i2s: Add S32_LE as support format
ASP/McBSP can support 8/16/20/24/32 bits word in theory. I have only tested
S16_LE and S32_LE, the other formats might not work so only extend the
supported formats with S32_LE for now.

ASoC: ti: davinci-i2s: Move the XSYNCERR workaround to .prepare callback
Currently the driver uses snd_soc_rtdcom_lookup() in it's mcbsp_start
function to try to stop/restart the DMA as the initial XSYNCERR workaround
need to be done before the DMA is armed.

There are couple of things wrong with this:
- the driver crashes with NULL pointer dereference as the
  component->driver->ops is actually NULL
- the driver should not use snd_soc_rtdcom_lookup() in the first place
- Fiddling with DMA is never a good thing

Move the workaround handling to .prepare which is called before the DMA is
armed, so it complies with the requirements.

ASoC: ti: Merge davinci and omap directories
Create new directory to contain all Texas Instruments specific DAI,
platform and machine drivers instead of scattering them under davinci and
omap directories.

There is already inter dependency between the two directories becasue of
McASP (on dra7x it is serviced by sDMA, not EDMA).

With the upcoming AM654 we will need to introduce new platform driver for
UDMA and it does not fit under davinci, nor under omap.

With the move I have restructured the Kconfig to be more usable in the era
of simple-sound-card:
CPU DAIs can be selected individually and they will select the platform
driver they can be served with.

To avoid breakage, I have moved over deprecated Kconfig options so
defconfig builds will work without regression.
