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.
