[PATCH 3/3] ARM: dts: marvell: add support for D-Link DNS-320L

[Zoltan HERPAI]

Dual-slot NAS based on Marvell Kirkwood.

Specifications:
 - Marvell 88F6702 @1GHz
 - 256Mb RAM
 - 128Mb NAND
 - 1x GbE LAN (Marvell 88E1318R)
 - 1x USB 2.0
 - 2x SATA
 - Weltrend WT69P3 ("supervisor" MCU chip)
 - Serial on J2 (115200,8n1)
 - Newer bootROM so kwboot-ing via serial is possible
