ASoC: adau1372: correct PGA enable & mute bit

The DAPM control for PGAx uses the PGA mute bit for
power management. This bit is active high but is set to
non-inverted (ie when powering, it will mute).
The ALSA control "PGA x Capture Switch" uses the active
high PGA_ENx bit, but is set to inverted. So when
enabling this switch, the PGA gets disabled.

To correct the behaviour, invert both these bits.
