Sumit Gupta 2401dc4dcd memory: tegra: Add Tegra264 MC and EMC support 
Add support to enable Memory Controller (MC) and External Memory
Controller (EMC) drivers for Tegra264. The nodes for MC and EMC are
mostly the same as Tegra234 but differ in number of channels and
interrupt numbers.

The patch also adds the bandwidth manager definitions required for
Tegra264 and uses them to populate the memory client table. All of
these are needed to properly enable memory interconnect (ICC) support.
