ARM: mvebu: add Device Tree description of the Armada 380/385 SoCs

The Armada 380 and 385 SoCs are new SoCs from Marvell, based on a
Cortex-A9 cores (single core for 380, dual core for 385) and a number
of hardware blocks that are common with earlier SoCs from the mvebu
family.

The provided Device Tree describes the following parts of the SoC:

 * CPU
 * Device Bus
 * Clocks
 * Interrupt controllers: GIC and MPIC
 * GPIO controllers
 * I2C buses
 * L2 cache
 * MBus controller
 * Pinctrl
 * Serial
 * SPI buses
 * System controller (for reboot)
 * Timer
 * XOR engines
 * PCIe controllers
 * Network interfaces
