[PATCH v3 1/5] ASoC: codecs: wsa883x: fix PA volume control

[Johan Hovold <johan+linaro@xxxxxxxxxx>]

The PA gain can be set in steps of 1.5 dB from -3 dB to 18 dB, that is,
in fifteen levels.

Fix the range of the PA volume control to avoid having the first
sixteen levels all map to -3 dB.

Note that level 0 (-3 dB) does not mute the PA so the mute flag should
also not be set.

Fixes: cdb09e623143 ("ASoC: codecs: wsa883x: add control, dapm widgets and map")
