Aaron Durbin 0dff57dd7a cbmem: switch over to imd-based cbmem
By design, the imd library still provdes dynamic growth so that
feature is consistent.  The imd-based cbmem packs small allocations
into a larger entry using a tiered imd. The following examples show
the reduced fragmentation and reduced memory usage.

Before with dynamic cbmem:
CBMEM ROOT  0. 023ff000 00001000
aaaabbbb    1. 023fe000 00001000
aaaabbbc    2. 023fd000 00001000
aaaabbbe    3. 023fc000 00001000
aaaacccc    4. 023fa000 00002000
aaaacccd    5. 023f9000 00001000
ROMSTAGE    6. 023f8000 00001000
CONSOLE     7. 023d8000 00020000
COREBOOT    8. 023d6000 00002000

After with tiered imd:
IMD ROOT    0. 023ff000 00001000
IMD SMALL   1. 023fe000 00001000
aaaacccc    2. 023fc000 00001060
aaaacccd    3. 023fb000 000007cf
CONSOLE     4. 023db000 00020000
COREBOOT    5. 023d9000 00002000
IMD small region:
  IMD ROOT    0. 023fec00 00000400
  aaaabbbb    1. 023febe0 00000020
  aaaabbbc    2. 023feba0 00000040
  aaaabbbe    3. 023feb20 00000080
  ROMSTAGE    4. 023feb00 00000004

Side note: this CL provides a basis for what hoops one needs to
jump through when there are not writeable global variables on
a particular platform in the early stages.
