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.

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.

In order to move common structure to fsl_asrc_common.h
we change the name of asrc_priv to asrc, the asrc_priv
will be used by new struct fsl_asrc_priv.

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.

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.

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.

ASRFSTi_IAEi has an 11-bit offset as its _SHIFT macro defines.
So this patch just fixes that.

ASRC need to enable the spba clock, when sdma is using share peripheral
script. In this case, there is two spba master port is used, if don't
enable the clock, the spba bus will have arbitration issue, which may
cause read/write wrong data from/to ASRC registers

The 'name' array is currently stored inside the fsl_asrc private structure only
for registering the interrupt name.
This can be simplified by registering it with dev_name() instead.

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.
