ASoC: fsl_asrc: Move common definition to fsl_asrc_common

There is a new ASRC included in i.MX serial platform, there
are some common definition can be shared with each other.
So move the common definition to a separate header file.

And add fsl_asrc_pair_priv and fsl_asrc_priv for
the variable specific for the module, which can be used
internally.

ASoC: fsl_asrc: Support new property fsl,asrc-format

In order to align with new ESARC, we add new property fsl,asrc-format.
The fsl,asrc-format can replace the fsl,asrc-width, driver
can accept format from devicetree, don't need to convert it to
format through width.

ASoC: fsl_asrc: Add support for imx8qm & imx8qxp

There are two asrc module in imx8qm & imx8qxp, each module has
different clock configuration, and the DMA type is EDMA.

So in this patch, we define the new clocks, refine the clock map,
and include struct fsl_asrc_soc_data for different soc usage.

The EDMA channel is fixed with each dma request, one dma request
corresponding to one dma channel. So we need to request dma
channel with dma request of asrc module.

ASoC: fsl_asrc: Fix error with S24_3LE format bitstream in i.MX8

There is error "aplay: pcm_write:2023: write error: Input/output error"
on i.MX8QM/i.MX8QXP platform for S24_3LE format.

In i.MX8QM/i.MX8QXP, the DMA is EDMA, which don't support 24bit
sample, but we didn't add any constraint, that cause issues.

So we need to query the caps of dma, then update the hw parameters
according to the caps.

ASoC: fsl_asrc: Use in(out)put_format instead of in(out)put_word_width

snd_pcm_format_t is more formal than enum asrc_word_width, which has
two property, width and physical width, which is more accurate than
enum asrc_word_width. So it is better to use in(out)put_format
instead of in(out)put_word_width.

ASoC: fsl_asrc: Add ASRC ASoC CPU DAI and platform drivers

The Asynchronous Sample Rate Converter (ASRC) converts the sampling rate of a
signal associated with an input clock into a signal associated with a different
output clock. The driver currently works as a Front End of DPCM with other Back
Ends DAI links such as ESAI<->CS42888 and SSI<->WM8962 and SAI. It converts the
original sample rate to a common rate supported by Back Ends for playback while
converts the common rate of Back Ends to a desired rate for capture. It has 3
pairs to support three different substreams within totally 10 channels.
