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.
