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.
