configs/raspberrypi0w_defconfig: new defconfig for Raspberry Pi Zero W

Up to now, Raspberry Pi Zero W (rpi0w) could be built with the normal
raspberrypi0_defconfig. However, then you don't have support for the
Bluetooth out-of-the-box, which makes using a W a bit pointless.

Therefore, create a separate defconfig for the W. It is a copy of
raspberrypi0_defconfig with the following changes:
 - Add DT overlays (from rpi-firmware) to support Bluetooth.
 - Pass --add-pi3-miniuart-bt-overlay to post-image.sh.

Since there is now a separate raspberrypi0w_defconfig, the W support
can be removed from raspberrypi0_defconfig.
