The previous patch increased the FIR length but it also triggered
a numerical issue in FIR design with long minimum phase filters. The
filter became essentially a band-stop filter and causes difficulties
in test of EQ component. Also the equalizer sounds subjectively
bad. The fix is to change the design to linear phase that always
converges.

How to use sof-ctl tool ========================= This tool helps to access the ext bytes or tlv bytes control of SOF components (like equalizer eq_iir and eq_fir). Please find the documentation in https://thesofproject.github.io/latest/getting_started/index.html for more information.
