arm64: tegra: Add CPU OPP tables for Tegra194

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 even though the table data is
same because the bandwidth request is per cluster. This is done
because OPP framework creates a single icc path and hence single
bandwidth request if the table is marked as 'opp-shared' and shared
among all clusters. For us, the OPP table data is same but the MC
Client ID argument to interconnects property is different for each
cluster. So, having per cluster table makes different icc path for
each cluster and helps to make per cluster BW requests.
