mb/google/brox: Create new Brox baseboard

This CL is just getting the initial brox framework to get the
baseboard building.  Copied files from brask baseboard and tried to
remove contents of some files like the device tree and memory IDs.
Added support for memory part "MT62F512M32D2DR-031 WT:B", mapped to
DRAM ID 0.
