mainboard/ocp/monolake: Initial commit

This patch does the following:
1. Copies mainboard/intel/camelback_fsp to mainboard/ocp/monolake
2. Adds Kconfig files to mainboard/ocp
3. Makes minor board-specific changes (board_info.txt, Kconfig
variables)

The OCP Mono Lake platform consists of up to 4 single-socket Xeon
D-1500 microservers in a Yosemite v1 chassis. More info is available
at http://www.opencompute.org/wiki/Server/SpecsAndDesigns.
