The Armada 385 RD board is the reference design 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 bus
* Serial port
* SPI bus, with a SPI flash
* PCIe interface

Changelog:
v1 -> v2:
- used the phy-mode "rgmii-id" to be able to work with the Marvell PHY
driver enabled
- put the ethernet nodes in the address order, as it has no effect to
change ti at this level (should be done at dtsi level)
- inverted the phy devices (which was improperly assigned in v1)
- added the vendor prefix for the SPI flash
