[PATCH for 8.2] ppc/amigaone: Allow running without firmware image

[BALATON Zoltan]

The machine uses a modified U-Boot under GPL license but the sources
of it are lost with only a binary available so it cannot be included
in QEMU. Allow running without the firmware image by specifying -bios
none which can be used when calling a boot loader directly which does
not need the firmware and thus simplifying booting guests.

Please merge for 8.2 as ir allows booting AmigaOS simpler without
having to download separate firmware.
