aliguori 6295e564f7 Remove nodisk_ok machine feature (Jan Kiszka) 
All archs have some kind of firmware to load and can be fine with it
already. So there is not much use in enforcing the presence of a disk.
If the system setup requires one, the user will notice it anyway once
the firmware/bios fails to boot from it.
