1) Format "wm8994-path.c", "wm8994.c", etc after kernel codingstyle.
2) Ajust wm8994 register setting when switching between playback and capture
playback path won't operate capture related power registers,
neither will capture.
This can solve the sound loss when switching between the two frequently.
3) Optimize audio code. Delete useless code, ajust the order of some codes, change macro defination etc.
4) Add macro "HIGH_VOLUME" in wm8994-path.c, enable it can get higher volume during playback.
5) This update include previous commit:
