ARM: mvebu: add support for the new Armada 385 based Linksys boards
This patch adds support for the Linksys WRT1200AC (Caiman) and
the Linksys WRT1900AC v2 (Cobra).
Both boards have:
- 2 Marvell 88W8864 radios
- 1 USB 3.0 port
- 1 USB 2.0/eSATAp port
- 2 Ethernet interfaces connected to a 88E6176 switch (1x WAN + 4x LAN)
- 128MB NAND flash
- 512MB RAM
