cpufreq: qcom-hw: Add register offsets for non-epss devices

Update the cpufreq hardware register offsets data for non EPSS devices to
be able to parse the LUTs of frequency and voltage.

Re-introduce the commit '00319840a4af ("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.
