In order to not expose the cbmem data structures to userland
that are used by coreboot internally add each of the cbmem
entries to a coreboot table record. The payload ABI uses
coreboot tables so this just provides a shortcut for cbmem
entries which were manually added previously by doing the
work on behalf of all entries.
A cursor structure and associated functions are added to
the imd code for walking the entries in order to be placed
in the coreboot tables. Additionally a struct lb_cbmem_entry
is added that lists the base address, size, and id of the
cbmem entry.
BUG=chrome-os-partner:43731
BRANCH=None
TEST=Booted glados. View coreboot table entries with cbmem.

It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.
This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

A tiered imd allows for both small and large allocations. The
small allocations are packed into a large region. Utilizing a
tiered imd reduces internal fragmentation within the imd.

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.
