This patch adds for EQ tests and presets switch development a
bundle with five presets: flat, loudness, bass-boost, band-pass,
and high-pass. The m4 file is used by including to topologies. The
text format file is for sof-ctl.
The added code to script example_iir_eq.m is included. The blob is
also useful for testing multi-part IPC for EQ component. The existing
examples were not large enough to exercise the feature.
