Some new machines use the "ibm,dynamic-reconfiguration-memory" property
to provide memory layout information, rather than via memory nodes.
There is a bug in the code to parse this property for start addresses over
4GB, we throw away the high bits and add apparently duplicate regions. This
results in a BUG() in free_bootmem_core().
