[PATCH 12/16] layerscape: use the lmb API's to add RAM memory

[Sughosh Ganu]

The EFI memory allocations are now being done through the LMB module,
and hence the memory map is maintained by the LMB module. Use the
lmb_arch_add_memory() API function to add the usable RAM memory to the
LMB's memory map.
