[tegra ALSA] Enable mic jack detection
Added support on Mic jack detection on Tegra.
- External mic jack detection could be probed by trigger an interrupt
via specific gpio or pull-up a generic gpio pin. The patch enabled the
later option.
- Tegra reference boards have gpio to switch external mic and internal
mic. The switching is done in the patch automatically once jack
happened.
