Revert "cpufreq: tegra186: Share policy per cluster"

This reverts commit ac64f0e893 which is
upstream commit be4ae8c19492cd6d5de61ccb34ffb3f5ede5eec8.

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.
