Add Realtek ALC5631/RT5631 codec support to the Tegra ASoC machine driver.
The RT5631 codec is found on devices like ASUS Transformer TF201, TF700T
and other Tegra-based Android tablets.

This is how downstream handled mclk rate for RT5631.

That doesn't mean it shouldn't be fixed or improved.

If the device doesn't have a distinct mic jack then it's not ideal to talk about there being one (as opposed to the microphone on the headset jack).
