[PATCH 6.10 0/5] ASoC: SOF: ipc4-topology: Fix nhlt configuration blob selection

[Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx>]

Hi,

the existing logic to pick a DMIC blob is based on several historical assumptions
that the NHLT in BIOS always contains 32-bits per sample type (first patch, [1]).

The other issue with the existing logic is that it was designed to care only
about the bit depth of the format and fails to find the existing and correct
blob when rate/channels are different on the FE side compared to what we should
be using on the DAI side (we have components in path which can change
rate/channel count).

These issues have not been observed in past but with new MTL based (Windows)
laptops and new topologies to enhance the audio quality, we started to see weird
issues around how our assumptions of vendors failed.

Since some NHLT blob handling cleanup has been done for 6.10, this series will
complete that work to cover even cases that we don't anticipate to see.
