qcom-cpufreq: Notify the current frequency to the topology driver 



The topology driver keeps track of the current capacity of a CPU
and make it available via arch_scale_freq_capacity(). The PELT
load tracking in the scheduler and energy-aware task placement
are the clients of this API. Hence notify the new frequency to the
topology driver during frequency transition.
