A reg can encode multiple regions, by just listing them one after the
other. It'll be in the generic docs about reg properties I expect,
there's nothing special about a reg property in a memory node in this
regard.

Xen parses these just fine, via the loop and use of device_tree_get_reg
in process_memory_node
