Each CPU DAI driver has its own defined DMA buffer size, so this patch just
drops the original one that uses a fixed size for all drivers and implements
a different DMA buffer size to each driver.

1. add 24bit format support.
2. enlarge the buffer size for ESAI.

For the sake of support asrc p2p, the sdma driver need to be updated.
1. Add another dma_request, p2p need two dma_request.
2. There are some cases which need to change the config after the
dma_request_channel. add dma_request config in dmaengine_slave_config().
3. add dma_request0 and dma_request1 in dma_slave_config for runtime config
in dmaengine_slave_config.

It removes the temporary custom DMA bindings from fsl_ssi driver and use
the generic one instead. It leaves imx-ssi drive unchanged regarding
those pcm flags by updating imx_pcm_dma_init() to let SSI driver decide
the flags.

Commit dbdf6b54340e1671439a4a5efbd15b7a0b14eacb upstream.
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.

Commit 88e89f5548a6e19bf837633f622764f2d1531748 upstream.
Create function imx_pcm_fiq_exit() to be paired with imx_pcm_fiq_init()
just like the pair of imx_pcm_dma_init() and imx_pcm_dma_exit().

Use the common DAI DMA data struct for fsl/imx, this allows us to use the common
helper function to configure the DMA slave config based on the DAI DMA data.

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.

When building modules with CONFIG_SND_IMX_SOC=m in imx_v6_v7_defconfig,
we will see the following link error.
LD [M] sound/soc/fsl/snd-soc-fsl-ssi.o

make[4]: *** [sound/soc/fsl/snd-soc-imx-pcm.o] Error 1
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.
