If the memory size given on the command line is equal to the
maximum size of memory defined by the hardware, there is no
"empty slot" after physical memory.
The following command
qemu-system-sparc -m 256
raised an assertion:
exec.c:2614: cpu_register_physical_memory_offset: Assertion `size' failed
This can be fixed either at the caller side (don't call empty_slot_init)
or in empty_slot_init (do nothing) when size == 0. The second solution
was choosen here because it is more robust.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.
This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

The empty_slot device emulates known to a bus but not connected devices.
