The remaining difference between raspberrypi0_defconfig raspberrypi0w_defconfig
wil be the usage of the pi3-miniuart-bt overlay. As there is no possibility to
enable/disable this on demand I think this is enough to justify a second
configuration (and keep the 'better' ttyAMA0 usage for serial console for
the basic raspberrypi0)...

Peter
