ALSA: ice1724 - aureon - modify WM8770 Master & DAC volume

The volume levels in original implementation are incorrect and does
not match the dB scale. The real range is linear (in the sense of
the dB scale) from 0dB to -100dB. Remove logaritmic table and make
all volumes from range 0dB..100dB.

The tests are in RedHat's bugzilla #540817.
