ASoC: cs35l56: Limit Speaker Volume to +12dB maximum

Change CS35L56_MAIN_RENDER_USER_VOLUME_MAX to 48, to limit the maximum value of the Speaker Volume control to +12dB. The minimum value is unchanged so that the default 0dB has the same integer control value. The original maximum of 400 (+100dB) was the largest value that can be mathematically handled by the DSP. The actual maximum amplification is +12dB. Signed-off-by: Richard Fitzgerald <[email protected]> Link: https://patch.msgid.link/[email protected] Signed-off-by: Mark Brown <[email protected]>
