ASoC: codecs: wcd938x: fix dB range for HPHL and HPHR
[ Upstream commit c03226ba15fe3c42d13907ec7d8536396602557b ]
dB range for HPHL and HPHR gains are from +6dB to -30dB in steps of
1.5dB with register values range from 0 to 24.
Current code maps these dB ranges incorrectly, fix them to allow proper
volume setting.
