core/linux-wandboard replaced kernel from @wandboard-org with 3.14 running on the Cubox-I

This replaces the wandboard kernel from the official @wandboard-org github account with a forked version of the kernel developed by @linux4kix. I added the dts and the rfkill driver from the @wandboard-org kernel.
See [this thread](http://forums.wandboard.org/viewtopic.php?f=12&t=666) in the wandboard forums.

This kernel runs fine on my wandboard quad rev b. In fact, it is more stable than the official kernels have ever been. Huge thanks to @linux4kix! I've been running this particular kernel for a few weeks now.
I have not tested this on other versions (single, dual) as well as revisions.

As my use case is mostly kodi (gpu, vpu, hdmi, no x11, sata, ethernet) I have not tested every single wandboard feature. I can say that the aforementioned as well as Wifi work. I have not tested other features like bluetooth, or gpios.

I'd be happy to receive some feedback on this.

Happy holidays!
