cpufreq: tegra186: Set target frequency for all cpus in policy

[ Upstream commit 0b1bb980fd7cae126ee3d59f817068a13e321b07 ]

The original commit set all cores in a cluster to a shared policy, but
did not update set_target to apply a frequency change to all cores for
the policy. This caused most cores to remain stuck at their boot
frequency.
