ASoC: jz4752b: Capture fixes

Merge series from Siarhei Volkau <lis8215@gmail.com>:

The patchset fixes:
 - Line In path stays powered off during capturing or
   bypass to mixer.
 - incorrectly represented dB values in alsamixer, et al.
 - incorrect represented Capture input selector in alsamixer
   in Playback tab.
 - wrong control selected as Capture Master
