[PATCH alsa-ucm-conf 1/2] codecs/rt5672: Move +12dB input boost from 'STO1 ADC Boost Gain' to 'ADC Capture Volume'

Both the 'STO1 ADC Boost Gain' and the 'ADC Capture Volume' controls are
digital and the 'ADC Capture Volume' control goes up to +30dB.

When adding hw-volume-control support adding the +12dB boost gain on to of
the max +30dB of 'ADC Capture Volume' is a bit too much.

So move the +12dB from the 'STO1 ADC Boost Gain' control to the
'ADC Capture Volume' control.

This way we keep the same setting for userspace which does not support
hw-volume-control, while getting a better range when we start using
'ADC Capture Volume' as hw-volume-control.
