6.10-stable review patch. If anyone has any objections, please let me know.

commit 244389bd42870640c4b5ef672a360da329b579ed upstream.
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.
