audio: volume: disable HIFI4 optimizations

HIFI4 has been disabled. HIFI3 is being used for
the volume component with peakVol.

There was a problem with test
test_01_09_peakvol_quality[44100Hz_16in16bit_1ch-0].
The main problem was with frequencies: 11025,
22050, 44100, 88200, 176400 Hz.
Because frame is different for these frequencies. For f=44100Hz
frame is equal 44 or 45. Some of the samples were simply not processed.

Changes to HIFI4 are not-trivial and failed to fix the problem.
However, HIFI3 is fully compatible and works properly.
Performance is worse by 1-2,5% in CPU cycle usage
but no glitches appear and all samples are processed correctly.
