This adds support for the wandboard (quad). I tested it on the quad rev B, other revisions and versions might work too.
I added the dts from wandboard-org/linux@225fbd6 plus some of the following patches from the wandboard-org/linux repo.
I also improved the rfkill driver to correctly reset the broadcom wifi/bt chip on boot.
