ASoC: SOF: ipc4-loader/topology: Query the CPC value from manifest
The manifest's firmware module configuration section contains the measured
CPC values along with a matching IBS/OBS values.
The CPC can be looked up by looking for a matching IBS/OBS entry.
In case of multiple matches we will use the highest CPC value.
If there is no mod_cfg or no CPC value (all 0) or no match was found then
print warning message and use 0 as CPC value.
