ARM: rpi: Add Raspberry Pi Zero W mini-uart support
Unlike the Raspberry Pi 1 and Raspberry Pi Zero, the Raspberry Pi Zero W
has its console pins on the header connected to the mini-uart, not the
PL011. The secondary PL011 UART is connected to the bluetooth module.
Set the mini-uart as default console and disable the PL011. That way we
can use the Raspberry Pi 1 image for the Zero W as well.
