We need to use input_audio_format and output_audio_format. Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
…BITS These two variables should only be used on the link side. It makes no sense to use them on the host-facing side of the DAI copier. FIXME: do we need to use 3 formats for the ALH copiers, in most cases there's really a need for a 32-bit format only? Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
The ALH copier only supports 32bits stereo on capture. All the additional formatls on the host copiers make no sense, and we also don't need to generate 4ch on the host side. It looks like the addition of the 1ch support was also problematic since the link always operates with 2ch. Signed-off-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

The topology2 maintenance continues to be problematic, we've added a number of "features" that were not completed to the end, due to copy-paste inertia and possibly lack of reviews.
While trying to enable the CHAIN_DMA mode for SoundWire, I found way too many complicated and unnecessary configurations.
This is an extremely invasive PR done with my extremely limited understanding of topology2, this needs careful testing and reviews.
FIXME: do we need to deal with multiple formats or can we assume that the ALH copiers always deal internally with 32-bits? I don't see the point of multiple options, only the host-copier host-facing formats should allow for more formats and conversions.
