hw/arm/raspi: Add the Raspberry Pi Zero machine
Similarly to the Pi A, the Pi Zero uses a BCM2835 SoC (ARMv6Z core).
The only difference between the revision 1.2 and 1.3 is the latter
exposes a CSI camera connector. As we do not implement the Unicam
peripheral, there is no point in exposing a camera connector :)
Therefore we choose to model the 1.2 revision.
Example booting the machine using content from [*]:
$ qemu-system-arm -M raspi0 -serial stdio \
-kernel raspberrypi/firmware/boot/kernel.img \
-dtb raspberrypi/firmware/boot/bcm2708-rpi-zero.dtb \
-append 'printk.time=0 earlycon=pl011,0x20201000 console=ttyAMA0'
