Add Tegra audio machine driver which is based on generic audio graph card driver. It re-uses most of the common stuff from audio graph driver and uses the same DT binding. Required Tegra specific customizations are done in the driver.

Do you really need to enumerate the frequencies? Wouldn't just checking srate % 11025 be enough to divide the set in two? Or just calculating the PLLA base rate by multiplying?
