coreboot: add imd library
The imd (internal memory database) library provides a way to
track memory regions by assigning ids to each region. The implementation
is a direct descendant of dynamic cbmem. The intent is to replace
the existing mechanisms which do similar things: dynamic cbmem, stage
cache, etc.
Differences between dynamic cbmem and imd:
- All structures/objects are relative to one another. There
are no absolute pointers serialized to memory.
- Allow limiting the size of the idm. i.e. provide a maximum
memory usage.
- Allow setting the size of the root structure which allows
control of the number of allocations to track.
