On i.mx8mscale, there are two sdma instances here, and common dma frameowrk will get channel dynamicly from any available channel whatever it's from the first sdma device or the second sdma device. But actually, some IP like SAI only work in sdma2 not sdma1. To make sure get sdma channel from the right sdma device, add index to match. Signed-off-by: Robin Gong <yibin.gong@nxp.com>
