arm: mvebu: Add DB-XC3-24G4XG board
The DB-XC3-24G4XG is a switch development board from Marvell. It can
either use and external CPU card such as the db-88f6820-amc or the
internal CPU that is integrated into the switch.
Add support for running U-Boot on the internal CPU and enable the USB,
SPI and NAND peripherals. For now this needs the bin_hdr from the
Marvell U-Boot for this board.
