ASoC: Intel: Skylake: Modify skl_dsp_set_dma_control API arguments
Set dma control ipc can be used to set the M/N divider, enable the clks. It takes different payload for different configuration. So modify the skl_dsp_set_dma_control API to take the size and node_id as argument. Signed-off-by: Jaikrishna Nemallapudi <jaikrishnax.nemallapudi@intel.com> Signed-off-by: Subhransu S.
