This adds a device tree for the CloudEngines PogoPlug series 4
NAS device. Inspired by out-of-tree boardfiles from ArchLinux
by Kevin Mihelich.

ChangeLog v1->v2:
- Use <dt-bindings/input/linux-event-codes.h>
- Specify default baud rate etc differently
- Rename LEDs "pogoplugv4*"
- Skip registering i2c0 as there is nothing on it

You should not need this. There are no other DTS files with it. As far
as i understand, the bootloader may add this to the DT blob before
passing it to the kernel, but i doubt the stock bootloader on your
device is doing it.
Otherwise this looks good.

Sure I can drop it.
