Audio: Fix Xtensa HiFi5 build for audio processing components

This patch avoids build error when testbench is built with a
Xtensa HiFi5 tool chain. The same issue is assumed to happen
in a normal firmware build as well.

A new macro SOF_USE_MIN_HIFI(minlevel, component) is added. It
can be used for the highest HiFi version optimization source to
allow build with a toolchain that is for a higher HiFi version.
E.g. build a HiFi4 module with toolchain for HiFi4 or HiFi5.

The updated components those got build issues are:
DCblock, DRC, FIR, TDFB, and IIR.
