This allows to play audio over S/PDIF and I2S simultaneously. The root of the problem is that audio components on Tegra share the same audio PLL, and thus, only a subset of rates can be supported if we want to play audio simultaneously. Filter out audio rates that don't match parent clock rate if device-tree has the nvidia,fixed-parent-rate property.

This creates problem for HDMI audio because it uses SPDIF and audio may not work if SPDIF's clock doesn't exactly match standard audio rate since some receivers may reject audio in that case.
