lmb: add a max parameter in the struct lmb_region
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. Signed-off-by: Patrick Delaunay <patrick.delaunay@foss.st.com>
