ASoC: WM8903: HP and Line out PGA/mixer DAPM fixes

Update the headphone and line out mixers and PGAs use the same logical
set of register bits and sequencing as the speaker mixer/PGA.

This allows ALSA controls for mute and volume on headphone and line out
to operate correctly.

Per conversation on alsa-devel, earlier datasheets indicated that the
POWER_MANAGEMENT_* register bits 0 and 1 were aliases to ANALOG_* register
bits 0 and 4, and hence only one copy of those bits was programmed.
However, later datasheets corrected this.
