    This commit adds the necessary code in the Marvell EBU PMSU driver to
    support dynamic frequency scaling. In essence, what this new code does
    is that it:

    * registers the frequency operating points supported by the CPU;

    * registers a clock notifier of the CPU clocks. The notifier function
    listens to the newly introduced APPLY_RATE_CHANGE event, and uses
    that to finalize the frequency transition by doing the part of the
    procedure that involves the PMSU;

    * registers a platform device for the cpufreq-generic driver, which
    will take care of the CPU frequency transitions.
