For the latest kernel device tree the max number of reserved regions in lmb library is reached: 8 with 5 reserved regions in device tree.
When a new region is added, the lmb allocation for the device tree relocation failed and boot with ramdisk failed.
This patch avoids this issue by increasing the max number of supported reserved memory in lmb library to 16.

Changes in v2: - Add CONFIG_LMB_USE_MAX_REGIONS=n and reduce LMB_MEMORY_REGIONS to reduce the used size in stack
