[PATCH v3 2/4] ASoC: fsl_asrc: Move common definition to fsl_asrc_common

Shengjiu Wang
2020-02-27T02:48:13Z

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_internal and fsl_asrc_internal for
the variable specific for the module, which can be used
internally.
