google/kukui: Revise FMAP layout for larger CBFS
Kukui with vboot enabled will build with `detachable_ui`, which needs
larger space in CBFS for more complicated assets. So we need to revise
FMAP sections:
- BOOTBLOCK (not really used) only needs <= 32K.
- GBB can be much smaller since assets moved from GBB to CBFS.
- FMAP is re-ordered (with the cost of less efficient in bsearch) so CBFS can
get larger continuous space.
- COREBOOT(CBFS) should take all space left.
Since FMAP and COREBOOT have changed location, the system will need to
reflash EC (which contains the new bootblock) as well.
BUG=b:123202015
TEST=Builds and boots on Kukui P1
