ASoC: da7219: Fix pole orientation detection on certain headsets
It has been recently found that certain 'active' headsets can
be mis-detected as OMTP instead of CTIA, causing obvious issus
with audio quality. This relates to increased resistances which
negatively impacts the pole detection circuitry within the device.
To counter this, ground switches on both headphone channels are
available to enable/disable and these allow for the detection
process to operate as intended, even with active headsets. This
commit adds control of the ground switches to the AAD logic.
