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.

The loudness EQ is changed to 250 taps to create large IPC
message type. It also improves subjective quality of this
effect with better bass response. The earlier version was
made very short to fit the that time IPC size limit.
