ASoC: dt-bindings: tegra20-i2s: Document new nvidia,fixed-parent-rate property 



Document new nvidia,fixed-parent-rate property which instructs that this
board wants parent clock to stay at a fixed rate. It allows to prevent
conflicts between audio components that share same parent PLL. For
instance, this property allows to have HDMI audio, speaker and headphones
in the system playing audio simultaneously, which is a common pattern for
consumer devices.
