mb/google/kukui: Extend FMAP to 8MB layout

The SPI flash component requirement for Kukui family is 8M so we should
update FMAP for that:

- Add more comments for alignment and size recommendation.
- Enlarge RO to 4M, and RW_SECTION_{A,B} both ~1.5M.
- BOOTBLOCK: 32K->128K, aligned with other ARM boards.
- Preserve RW_DDR_TRAINING for new calibration.
- Reorder the sections for better alignment.
- RW_MISC to contain RW sections that should be merged when creating AU image.
