Setting assigned clock with a dependency on itself for k2g_clks
creates a circular dependency. Instead, Lets model the audio clock
as a assigned-clock configuration for mcasp and set it up as the
first clock assigned-clock to be satisfied. Following the standard
convention, we use null entries to indicate entries that doesn't need
to be programmed.
