coreboot: add memory pool infrastructure

Browse Source 
The memory pool infrastructure provides an allocator with
very simple free()ing semantics: only the most recent allocation
can be freed from the pool. However, it can be reset and when
not used any longer providing the entire region for future
allocations.
