In this patch the SSP0 BE's mode is changed from I2S mode to DSP_B
with 8 slots of 16 bits. 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.

This patch sets the SSP params based on FE and BE dai links
for kabylake machine driver that uses rt5663 and max98927 codecs
