cpufreq: qcom-hw: Update freq_scale from fast_switch path



The freq_scale maintained by the topology driver needs to be
updated when the frequency is transitioned. Without this,
the current capacity of a CPU metric gets broken in the scheduler.

The current code calls arch_set_freq_scale() from the target_index
method but not from the fast_switch method. Fix this.
