I wonder if it would make more sense to pass an actual clock reference
here. If valid, then reconfigure the period to the value returned by
clk_get_rate(). It would avoid yet another DT binding. If we make the
clock optional, then we won't affect any other platforms. The clock
itself could be a regular fixed clock node.
