ASoC: SOF: ipc4: Add macros for chain-dma message bits
In the chained DMA mode, the firmware allocates buffers for the host and link DMA, and takes care of copying data between host- and link-DMA buffers in a low-latency thread. This is different to a regular pipeline, no processing is allowed, and the connection between host- and link DMA is handled with a dedicated IPC. This patch exposes the macros needed to create the required IPC messages.
