ASoC: SOF: ipc4: store number of playback/capture streams
The CHAIN_DMA IPC needs the number of playback streams as a start
offset for the dma_id of a capture stream.
This offset can be retrieved on Intel platforms from the GCAP
information, and stored in the sof_ipc4_fw_data structure.
One could argue that the fields added are not really dependent on any
firmware definitions but rather on hardware capabilities, but they are
required for the IPC CHAIN_DMA definitions so adding them in
ipc4_fw_data isn't completely silly.
The CHAIN_DMA IPC is currently only functional on Intel HDaudio DMAs,
and gated by the snd_sof_is_chain_dma_supported() helper.
