topology2: sdw-dmic-generic: add eqiir to control DC offset 

For some reason we had the EQIIR for topology1/IPC3 but we didn't add
it for topology2/IPC4.  All recordings show there's a strong DC offset
with RT722 and other codecs, so let's add this component by default in
the non-passthrough cases.

The widget is added in the scope of a pipeline, so that the
auto-generated instance is not handled at a global level.
