VAG power control is improved to fit the manual. This fixes as
minimum one bug: if customer muxes Headphone to Line-In right after boot
w/o playing any sound, the VAG power remains off that leads to poor
sound quality from line-in.
I.e. after boot:
- Connect sound source to Line-In jack;
- Connect headphone to HP jack;
- Run following commands:
$ amixer set 'Headphone' 80%
$ amixer set 'Headphone Mux' LINE_IN
Also this series includes fixes of non-important bugs in sgtl5000 codec
driver.
Fix patch formatting in patchset v2.

SGTL5000_SMALL_POP is a bit mask, not a value. Usage of
correct definition makes device probing code more clear.

To enable "zero cross detect" for ADC/HP, change
HP_ZCD_EN/ADC_ZCD_EN bits only instead of writing the whole
CHIP_ANA_CTRL register.

source can be assigned automatically.

Change VAG power on/off control according to the following algorithm:
- turn VAG power ON on the 1st incoming event.
- keep it ON if there is any active VAG consumer (ADC/DAC/HP/Line-In).
- turn VAG power OFF when there is the latest consumer's pre-down event
come.
- always delay after VAG power OFF to avoid pop.
- delay after VAG power ON if the initiative consumer is Line-In, this
prevents pop during line-in muxing.
Also, according to the manual, to avoid any pops/clicks,
the outputs should be muted during input/output
routing changes.
