Define the set of CCUs and provided clocks sufficient to satisfy the needs of all the existing clock references for BCM21664. Replace the "fake" fixed-rate clocks used previously with "real" ones. Note that only the minimal set of these clocks and CCUs is defined here. More clock definitions will need to be added as required by the addition of additional drivers.
