memory: add API for observing updates to the physical memory map
Add an API that allows a client to observe changes in the global memory map: - region added (possibly with logging enabled) - region removed (possibly with logging enabled) - logging started on a region - logging stopped on a region - global logging started - global logging removed This API will eventually replace cpu_register_physical_memory_client().
