boards/raspberrypi0: new board
Add support for the rpi-0, which is basically a rpi (model A+) in a smaller form-factor. This one does not have an ethernet port, so we just remove it from the configuration (or we could use the existing rasbperrypi_defconfig and suffer from a longer boot time because of the waiting for eth0).
