Topology: NHLT: Intel: Fix DMA slots config in SSP blob

This fixes a mistake in function ssp_calculate_intern_v30(). The rx_dir[0] and tx_dir[0] value was hard-coded to 0x3 for typical stereo slots configuration. It should be instead retrieved from topology parameters for the SSP. Closes: #289 Signed-off-by: Seppo Ingalsuo <[email protected]> Signed-off-by: Jaroslav Kysela <[email protected]>
