From: Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx>
In case of capture and when the DAI copier have single bit depth supported
on it's input side we should use this format instead of the one in
fe_params.
Regardless of the stream direction for the NHLT blob lookup when the DAI
copier only supports single bit depth on the DAI side we should only look
for a blob which matches with this single configuration.
For DMIC if the DAI copier supports multiple bit depths, try to request
32-bit blob first if the requested bit depth is 16-bit.
If the 32-bit blob is available then look for marching (32-bit) copier
format to make sure that both the blob and copier have correct parameters.
