As the ssi is not the only cpu dai, there are esai, spdif, sai.
and imx_pcm_dma can be used by all of them. Especially ESAI need
a larger DMA buffer size. So Add dedicated DMA buffer for each cpu
dai.

Building imx_v6_v7_defconfig with all audio drivers as modules results in
the folowing build error:

ERROR: "imx_pcm_dma_init" [sound/soc/fsl/snd-soc-imx-ssi.ko] undefined!

Fix this by allowing SND_SOC_IMX_PCM_FIQ and SND_SOC_IMX_PCM_DMA to be also
built as modules and by using 'IS_ENABLED' to cover the module case.

Let CPU DAI drivers set SDMA periperal type directly to support more
dma types(SPDIF, ESAI) other than only two for SSI.
This will easily allow some non-SSI drivers to use the imx-pcm-dma
as well.

With imx-pcm-dma moving to generic dmaengine pcm driver and the removal
of imx-pcm-audio/imx-fiq-pcm-audio platform device use, now imx-pcm
driver contains a few functions that are only used by imx-pcm-fiq.c.
Move these functions into imx-pcm-fiq.c and remove imx-pcm.c completely.

Currently the imx_dma_data struct, which gets passed to the dmaengine driver, is
allocated and constructed in the pcm driver from the data stored in the
dma_params struct. The dma_params struct gets passed to the pcm driver from the
dai driver. Instead of going this route of indirection embed the dma_data struct
directly into the dma_params struct and let the dai driver fill it in. This
allows us to simplify the imx-pcm-dma driver quite a bit, since it doesn't have
care about memory managing the imx_dma_data struct anymore.

The module snd-soc-imx-pcm is designed to link imx-pcm.o with
imx-pcm-dma.o or imx-pcm-fiq.o depending on if option SND_SOC_IMX_PCM_DMA
or SND_SOC_IMX_PCM_FIQ is enabled. Both imx-pcm-dma and imx-pcm-fiq
register their own module_platform_driver. However, these two options
are not mutually exclusive and can be enabled together. And that's
why we see above multiple init_module definition error.
Instead of having both imx-pcm-dma and imx-pcm-fiq register their
own platform_driver, we should do only once in imx-pcm.c. Using
platform_device_id to distinguish between imx-pcm-dma and imx-pcm-fiq,
we can run-time call imx-pcm-dma/fiq specific initialization in .probe
hook to have module snd-soc-imx-pcm work for both cases.

Freescale PowerPC and ARM/IMX families share the same SSI IP block.
The patch merges sound/soc/imx into sound/soc/fsl, so that the possible
code sharing and consolidation can happen.
This is a plain merge, except that menuconfig SND_POWERPC_SOC is added
in Kconfig for PowerPC platform as a correspondence to SND_IMX_SOC for
IMX platform.
