Adding Interconnect framework support to dynamically set the DRAM
bandwidth from different clients. Both the MC and EMC drivers are
added as ICC providers. The path for any request will be:
MC-Client[1-n] -> MC -> EMC -> EMEM/DRAM
MC clients will request for bandwidth to the MC driver which will
pass the tegra icc node having current request info to the EMC driver.
The EMC driver will send the BPMP Client ID, Client type and bandwidth
request info to the BPMP-FW where the final DRAM freq for achieving the
requested bandwidth is set based on the passed parameters.
