Audio: Disable UART debug cable detection to support active headphone devicesandroid-tegra3-grouper-3.1-jb-fr1
Since active headphone devices could be mis-detected as UART debug cable,
we disable UART debug cable detection by default to workaround the limitation.
All insertion will be treated as headphone.
