[RFC PATCH 11/31] lib: Kconfig: add a config symbol for getting memory map updates

[Sughosh Ganu]

Add a Kconfig symbol to enable getting updates on any memory map
changes that might be done by some other module. This notification
mechanism can then be used to have a synchronous view of allocated and
free memory.
