In order to support new EASRC and simplify the code structure, We decide to share the common structure between them. This bring a problem that EASRC accept format directly from devicetree, but ASRC accept width from devicetree.
In order to align with new ESARC, we add new property fsl,asrc-format. The fsl,asrc-format can replace the fsl,asrc-width, then driver can accept format from devicetree, don't need to convert it to format through width.
