Add new compatible string 'fsl,imx952-asrc' for i.MX952 platform, below are the differences that make this ASRC not fallback compatible with other platforms.
1) There is a power domain on i.MX952 for the wakeupmix system where ASRC is in. But it is enabled by default, ASRC device don't need to enable it, so it is optional for i.MX952. 2) The clock sources of ASRC are different on i.MX952. 3) There is a limitation on i.MX952 that DMA request is not cleared at the end of conversion with dma slave mode. Which causes sample is dropped from the input fifo on the second time if DMA is triggered before the client device and DMA may copy wrong data from output fifo as the output fifo is not ready in the beginning. So there is specially handling in the driver.
