EQ Tool: Output topology m4 binary control style configuration data 

This patch adds export function for the m4 syntax bytes data and adds
the export of such blob to example designs. The example EQ designs are
edited to make this format export too.

In addition the example FIR length is adjusted to be near current IPC
length maximum (384) and improve the effect quality.
