ASoC: es8316: Simplify adc_pga_gain_tlv table
[ Upstream commit bb18c678754ce1514100fb4c0bf6113b5af36c48 ]
Most steps in this table are steps of 3dB (300 centi-dB), so we can
simplify the table.
This not only reduces the amount of space it takes inside the kernel,
this also makes alsa-lib's mixer code actually accept the table, where
as before this change alsa-lib saw the "ADC PGA Gain" control as a
control without a dB scale.
