board: cssi: Add new board MCR3000_2G
This adds a new board from CS GROUP. The board is called MCR3000_2G, and has a CPU board called CMPC885. That CPU board is shared with another equipment that will be added in a later patch. That board stores Ethernet MAC addresses in an EEPROM which is accessed using SPI bus. This patch was originally written by Charles Frey who's email address is not valid anymore as he left the company.
