ASoC: dt-bindings: fsl_asrc: add compatible string for imx8qm & imx8qxp 

Add compatible string "fsl,imx8qm-asrc" for imx8qm platform,
"fsl,imx8qxp-asrc" for imx8qxp platform.

There are two asrc modules in imx8qm & imx8qxp, the clock mapping is
different for each other, so add new property "fsl,asrc-clk-map"
to distinguish them.
