Add compatible string "fsl,imx8qm-asrc" for imx8qm platform. There are two asrc modules in imx8qm, the clock mapping is different for each other, so add new property "fsl,asrc-clk-map" to distinguish them. Signed-off-by: Shengjiu Wang <redacted> --- changes in v2 -none changes in v3 -use only one compatible string "fsl,imx8qm-asrc", -add new property "fsl,asrc-clk-map".
