powerpc: DTS file for the C2K

Support for the C2K cPCI Single Board Computer from GEFanuc
(PowerPC MPC7448 with a Marvell MV64460 chipset).
All features of the board are not supported yet, but the board
boots, flash works, all Ethernet ports are working and PCI
devices are all found (USB and SATA on PCI1 do not work yet).

Part 1 of 5: DTS file describing the board peripherals.  As far as I
know all peripherals except the FPGA are listed in there (I did not
include the FPGA because a lot of work is needed there).
