As the cpufreq-dt driver now supports platforms with multiple 'struct cpufreq_policy' instances (i.e. > 1 clock domains for CPUs), passing 'cpu_present_mask' isn't correct anymore. As every policy will have a set of CPUs and that may not be equal to 'cpu_present_mask' always. So, pass only mask of CPUs which are controlled by current policy.
