The memory map maintained by the LMB module is now persistent and
global. This memory map is being maintained through the alloced list
structure which can be extended at runtime -- there is one list for
the available memory, and one for the used memory. Allocate and
initialise these lists during the board init.

Changes since V2:
* Use if(CONFIG_IS_ENABLED(...)) in initr_lmb() instead of an #ifdef.
