    ipq806x: add missing scaling_available_frequencies for dedicated cpufreq
    
    Add missing scaling_available_frequencies sysfs entry for dedicated
    cpufreq driver.
    This sysfs entry is not standard and each cpufreq driver needs to
    provide it and declare it in the cpufreq driver struct attr.
