[ARM] add Marvell Kirkwood (88F6000) SoC support
The Marvell Kirkwood (88F6000) is a family of ARM SoCs based on a Shiva CPU core, and features a DDR2 controller, a x1 PCIe interface, a USB 2.0 interface, a SPI controller, a crypto accelerator, a TS interface, and IDMA/XOR engines, and depending on the model, also features one or two Gigabit Ethernet interfaces, two SATA II interfaces, one or two TWSI interfaces, one or two UARTs, a TDM/SLIC interface, a NAND controller, an I2S/SPDIF interface, and an SDIO interface. This patch adds supports for the Marvell DB-88F6281-BP Development Board and the RD-88F6192-NAS and the RD-88F6281 Reference Designs, enabling support for the PCIe interface, the USB interface, the ethernet interfaces, the SATA interfaces, the TWSI interfaces, the UARTs, and the NAND controller.
