Add support for Raspberry Pi Zero W (same as Pi Zero with
additional wireless and bluetooth support [1]).

According to [2] has the same serial console vs. bluetooth
problem as the Pi 3. Try the same fix (load pi3-miniuart-bt overlay).

Changes v1 -> v2:
  - add missing board/raspberrypi/genimage-raspberrypi0w.cfg

Untested (even not compile tested) because of lack of hardware...
