cpufreq: scpi: invoke frequency-invariance setter function 



Commit 343a8d17 (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().
