hw/ppc/spapr: Use machine_memory_devices_init()

Browse source 
Let's use our new helper and stop always allocating ms->device_memory.
There is no difference in common memory-device code anymore between
ms->device_memory being NULL or the size being 0. So we only have to
teach spapr code that ms->device_memory isn't always around.

We can now modify two maxram_size checks to rely on ms->device_memory
for detecting whether we have memory devices.
