arm64: tegra: Add CPU OPP tables for Tegra186

Browse Source 
Add OPP table and interconnects property to scale DDR frequency with
CPU frequency for better performance. Each operating point entry of
the OPP table has CPU freq to per MC channel bandwidth mapping. One
table is added for each cluster because the different cpu types have
different scaling curves.
