ASoC: tegra: Support coupled mic-hp detection

Browse Source 
This quirk is used for cases when there is GPIO which detects
any type of 3.5 Jack insertion and actual type of jack is defined
by other GPIO. 3.5 Jack GPIO generates interrupt and MIC GPIO
indicates type of Jack only if 3.5 Jack GPIO is active.
