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.
