Commit 10df350977b1 ("ASoC: Intel: Fix Audio DSP usage when IOMMU is enabled.") caused following regression in Baytrail SST:
baytrail-pcm-audio baytrail-pcm-audio: error: DMA alloc failed baytrail-pcm-audio baytrail-pcm-audio: error: failed to load firmware
Fix this by calling dma_coerce_mask_and_coherent() in sst_byt_init() with the same dma_dev device what is now used in sst_fw_new() when allocating the DMA buffer.
