arm: mvebu: Add support for Synology DS116 (Armada 385)

Synology DS116 is a NAS based on Marvell Armada 385 SoC.

Board Specification:

- Marvel MV88F6820 Dual Core at 1.8GHz
- 1 GiB DDR3 RAM
- 8MB Macronix mx25l6405d SPI flash
- I2C
- 2x USB 3.0
- 1x GBE LAN port (PHY: Marvell 88E1510)
- 1x SATA (6 Gbps)
- 3x LED
- PIC16F1829 (connected to uart1)
- GPIO fan
- serial console

Note that this patch depends on the add-support for Thecus N2350 patch:
