I built the dtb for the amazon instance (alpine), and get a bit
further. Feels like the wrong thing to do with the qemu setup as we
should probably have one which describes the emulated hardware. I'm a
little suprised that qemu-system-aarch64 does't have this - so I'm
probably still missing something in my understanding.
The amazon A1 instances has these devices. I guess we need ENA support
for Amazon's new hypervisors anyway... (SR-IOV).
