OK, let's allow overlapping, but make it explicit:
void cpu_register_memory_region_overlap(MemoryRegion *mr,
target_phys_addr_t addr,
int priority);
We need that ordering, so we need an interface. Regions registered via
cpu_register_memory_region must not overlap with existing one or we will
throw an hwerror. And they shall get a low default priority.
PCI BARs can overlap with anything. So any region can overlap with any other region.
