[PATCH v2 3/8] lmb: add a max parameter in the struct lmb_region

[Patrick Delaunay]

Add a max parameter in lmb_region struct to handle test
in lmb_add_region without using the MAX_LMB_REGIONS
define.
This patch allows to modify these size independently for
memory of reserved regions in the next patches.

Changes in v2:
- add a max parameter extracted from v1 [3/5]
