The ext bytes read response parsing needs a fix since it now includes
the ABI header. A warning is printed if max control size is reached.
The example configurations are also updated to contain the header.
The patch also includes new IIR and FIR setup for pass-through
configuration (for testing) that configures the EQ component to totally
pass the filter computation.
