Subject: [PATCH 16/16] ASoC: codecs: msm8916-wcd-digital: fix tlv min max range

on Qualcomm codecs gain tlv control specifies min max range as both
negative to positive numbers like

SOC_SINGLE_SX_TLV("... Volume", ..,  -84, 40, gain)

However with recent boundary checks added in commit 817f7c9335ec0
("ASoC: ops: Reject out of bounds values in snd_soc_put_volsw())
setting a value above 40 gain will fail.

So fix this min max range correctly to
SOC_SINGLE_SX_TLV("... Volume", ..,  0, 124, gain)
so that users can now set gain correctly

Fixes: ef8a4757a6db ("ASoC: msm8916-wcd-digital: Add sidetone support")
