Add a multicore configuration for the Terasic de0 nano FPGA development board. This SoC runs 2 OpenRISC CPUs at 50Mhz with 32MB ram, UART for console and GPIOs for LEDs.
This FPGA SoC is based on the simple-smp reference board and brings in devices from the de0 nano common DTSI file. A default config is added that brings together the device tree and driver setup.
