Merge series "ASoC: SOF: multi-cpu dais, IPC and Intel improvements for 5.7" from Pierre-Louis Bossart <[e-mail]>:

Corrections for compatibility with the multi-cpu dai check for
min-channels, IPC simplifications, and removal of unnecessary
boot-related code for Intel platforms.

Amery Song (2):
ASoC: SOF: Intel: hda: remove unnecessary ROM IPC filter function
ASoC: SOF: Intel: remove unnecessary waitq before loading firmware

Bard Liao (2):
ASoC: SOF: Intel: hda-dai: add stream capability
ASoC: SOF: topology: connect dai widget to all cpu-dais

Karol Trzcinski (2):
ASoC: SOF: Make sof_ipc_ext_data enum more rigid
ASoC: SOF: Remove SOF_IPC_EXT_DMA_BUFFER
