The OMTP pin define headsets can be mis-detected as line out
instead of OMTP, causing obvious issues with audio quality.
This patch is to put increased resistances within
the device at a suitable point.

To solve this issue better, the new mechanism setup
ground switches with conditional delay control
and these allow for more stabile detection process
to operate as intended. This conditional delay control
will not impact the hardware process
but use extra system resource.

This commit improves control of ground switches in the AAD logic.
