ASoC: SOF: ipc4-pcm: fixup dailink based on copier format

When a copier exposes a single format, we can fixup the BE dailink with
that format. This is helpful when some codec have format restrictions and
e.g. don't support a 32-bit format. In that case, the copier output
formats mirror that restriction in the topology file.

An alternate solution was suggested earlier using a dedicated topology
token. When specified, the token would be used to fix-up the dailink. The
main reason why this solution was chosen is that there is a risk of a
disconnect between token definition and copier format. With a single piece
of information as suggested in this patch, there are fewer risks of a bad
configuration.
