cpufreq: tegra194: save CPU data to avoid repeated SMP calls

Browse source

Currently, we make SMP call on every frequency set request to get the
physical 'CPU ID' and 'CLUSTER ID' for the target CPU. This change
optimizes the repeated calls by storing the physical IDs and the per
core frequency register offset for all CPUs during boot. Later this
info is used directly when required to set the frequency or read it
from ACTMON counters.
