This patch adds the device-tree definitions for
Western Digital MyBook Live NAS devices.
Technically, this devicetree file is shared by two, very
similar devices.
There's the My Book Live and the My Book Live Duo. WD's uboot
on the device will enable/disable the nodes for the device.
Ready to go images and install instruction can be found @OpenWrt.org
