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.
