MLK-16450-1: ASoC: fsl_hifi4: fix crash issue caused by memcpy()
When loop testing the hifi4 dirver, a random crash issue always
occur when doing memcpy() in decode function.
Have found that memcpy() is not suited to transfer data between
kernel space and user space, so use copy_from_user() and copy_
to_user() function to replace memcpy() to fix this issue.

The dmaengine_prep_slave_sg needs to use sg count returned
by dma_map_sg, not use sport->dma_tx_nents, because the return
value of dma_map_sg is not always same with "nents".
When enabling iommu for lpuart + edma, iommu framework may concatenate
