Commit 343a8d17fa8d ("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().
