ASoC: SOF: ipc4-pcm: fix dma_id for CHAIN_DMA capture

Browse source

The existing code uses (stream_tag - 1) for the host and link dma id.

This is correct for playback, but for capture this results in an
invalid dma_type being used. The firmware assumes that the dma_id for
capture is always larger than DAI_NUM_HDA_OUT

This patch adds the offset for num_playback_streams, filled on Intel
platforms with the value extracted from the hardware capabilities.
