UPSTREAM: 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.
