Add the base DTS for the AMCC PowerPC 405EZ Acadia evalution board. In addition to some of the normal PPC 40x peripherals, the Acadia board has: - 64 MiB PSRAM - NOR and NAND flash - Two USB 1.1 host ports - Two CAN 2.0 ports - ADC and DAC connectors - LCD display This adds the basic platform support to build from.
