c6d4a89775 ARM: tegra: Rename CPU and EMC OPP table device-tree nodes 
OPP table name now should start with "opp-table" and OPP entries
shouldn't contain commas and @ signs in accordance to the new schema
requirement. Reorganize CPU and EMC OPP table device-tree nodes.

881741fa44 ARM: tegra: Add EMC OPP and ICC properties to Tegra30 EMC and ACTMON device-tree nodes 
Add EMC OPP 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.
