[PATCH v4 11/13] ARM: mvebu: add Device Tree for the Armada 385 DB board

[Thomas Petazzoni]

The Armada 385 DB board is the development board from Marvell for the
Armada 385 SoC. This commit adds a Device Tree description for this
board, which enables the following features:

 * Network interfaces
 * I2C buses
 * SDIO
 * Serial port
 * SPI bus, with a SPI flash
 * PCIe interfaces
