cpufreq: scpi: invoke frequency-invariance setter function
Commit343a8d17fa
(cpufreq: scpi: remove arm_big_little dependency) changed the cpufreq driver on juno from arm_big_little to scpi. The scpi set_target function does not call the frequency-invariance setter function arch_set_freq_scale() like the arm_big_little set_target function does. As a result the task scheduler load and utilization signals are not frequency-invariant on this platform anymore. Fix this by adding a call to arch_set_freq_scale() into scpi_cpufreq_set_target().
