ppc/ppc405: Rework FW load
QEMU installs a custom U-Boot in-memory descriptor to share board
information with Linux, which means that the QEMU machine was
initially designed to support booting Linux directly without using the
loaded FW. But, it's not that simple because the CPU still starts at
address 0xfffffffc where nothing is currently mapped. Support must
have been broken these last years.
Since we can not find a "ppc405_rom.bin" firmware file, request one to
be specified on the command line. A consequence of this change is that
the machine can be booted directly from Linux without any FW being
loaded. This is still broken and the CPU start address will be fixed
in the next changes.
