ASoC: ti: fix davinci_mcasp_probe dependencies
The SND_SOC_DAVINCI_MCASP driver can use either edma or sdma as
a back-end, and it takes the presence of the respective dma engine
drivers in the configuration as an indication to which ones should be
built. However, this is flawed in multiple ways:

- With CONFIG_TI_EDMA=m and CONFIG_SND_SOC_DAVINCI_MCASP=y,
  is enabled as =m, and we get a link error:
  sound/soc/ti/davinci-mcasp.o: In function `davinci_mcasp_probe':
  davinci-mcasp.c:(.text+0x930): undefined reference to `edma_pcm_platform_register'

- When CONFIG_SND_SOC_DAVINCI_MCASP=m has already been selected by
  another driver, the same link error appears even if CONFIG_TI_EDMA
  is disabled

There are possibly other issues here, but it seems that the only reasonable
solution is to always build both SND_SOC_TI_EDMA_PCM and
SND_SOC_TI_SDMA_PCM as a dependency here. Both are fairly small and
do not have any other compile-time dependencies, so the cost is
very small, and makes the configuration stage much more consistent.

ASoC: ams-delta: remove duplicate 'const'
clang points out that SOC_ENUM_SINGLE_EXT_DECL() contains a 'const'
modifier already, so adding another one does not make it more const:

sound/soc/ti/ams-delta.c:203:14: error: duplicate 'const' declaration specifier [-Werror,-Wduplicate-decl-specifier]
static const SOC_ENUM_SINGLE_EXT_DECL(ams_delta_audio_enum,
             ^
include/sound/soc.h:351:2: note: expanded from macro 'SOC_ENUM_SINGLE_EXT_DECL'
        const struct soc_enum name = SOC_ENUM_SINGLE_EXT(ARRAY_SIZE(xtexts), xtexts)

ASoC: ti: remove compat dma probing
After running into a link error:

sound/soc/ti/edma-pcm.o:(.rodata+0x18): undefined reference to `edma_filter_fn'

I checked all users of this, and they have new-style 'dma_slave_map' tables,
so none of them should still need it. Removing the associated lines
simplifies the code and avoids the build-time dependency on the
respective dmaengine drivers.

ASoC: davinci-mcasp: Fix clang warning without CONFIG_PM
Building with clang shows a variable that is only used by the
suspend/resume functions but defined outside of their #ifdef block:

sound/soc/ti/davinci-mcasp.c:48:12: error: variable 'context_regs' is not needed and will not be emitted

We commonly fix these by marking the PM functions as __maybe_unused,
but here that would grow the davinci_mcasp structure, so instead
add another #ifdef here.

ASoC: ti: davinci-mcasp: Add support for GPIO mode of the pins
All McASP pin can be configured as GPIO.
Add gpiochip support for McASP and only enable it when the
gpio-controller is present in the DT node.

ASoC: ti: davinci-mcasp: No need for IS_MODULE/BUILTIN check for pcm driver
Since the platform drivers are selected by the DAI drivers (including
McASP) there is no longer a need to check whether the modules are built-in
or module.

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.
