ASoC: codecs: jz4725b: use right control for Capture Volume

[ Upstream commit 1538e2c ]

Line In Bypass control is used as Master Capture at the moment
this is completely incorrect.

Current control routed to Mixer instead of ADC, thus can't affect
Capture path. ADC control shall be used instead.

ADC volume control parameters are different, so the patch fixes that
as well. Manual says (16.6.3.2 Programmable input attenuation amplifier:
PGATM) that gain varies in range 0dB..22.5dB with 1.5dB step.
