It enables 4 slot for IV feedback and 2 slots for playback on max98927 for kabylake machine driver The layout of SSP0 Tx and Rx slots is as follows; 1. Playback uses Tx slots 0 and 1 2. Capture uses Rx slots 4,5,6,7. Slots 0 through 3 of Rx are used by DMIC codec RT5514 in another flavor of Kabylake platform. We are using the same slots 4 through 7 on all Kabylake platforms for max98927 in order to reuse same NHLT configuration.
