Revert "cpufreq: tegra186: Share policy per cluster"

This reverts commit 89172666 which is
upstream commit be4ae8c1.

This commit is causing a suspend regression on Tegra186 Jetson TX2 with
Linux v6.12.y kernels. This is not seen with Linux v6.15 that includes
this change but indicates that there are there changes missing.
Therefore, revert this change.
