[alsa-devel] [PATCH 5/9] ASoC: Intel: Skylake: Update for ssp node index in copier cfg

From: Jeeja KP <jeeja.kp at intel.com>

DSP firmware has interface change for SSP node index structure.
New FW interface removes the dual_mono field and adds 4 bits for
TDM slot group index. This patch updates the ssp dma to align with
the DSP firmware structure.
