ARM: tegra: Add EMC OPP and ICC properties to Tegra124 EMC and ACTMON device-tree nodes
Add EMC OPP DVFS/DFS tables and interconnect paths that will be used for dynamic memory bandwidth scaling based on memory utilization statistics. Update board device-trees by removing unsupported EMC OPPs. Note that ACTMON watches all memory interconnect paths, but we use a single CPU-READ interconnect path for driving memory bandwidth, for simplicity.
