[PATCH v2 17/32] lmb: init: initialise the lmb data structures during board init

[Sughosh Ganu]

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 V1:
* Move the initr_lmb() function to board_r.c
* Call lmb_init() from spl.c instead of initr_lmb().
