google/kukui: Revise FMAP firmware layout
Adjust FMAP sections that - ELOG only needs 4K (by driver limitation) - SHARED_DATA only needs 4K or less (for netboot params) - SMMSTORE is probably not needed since UEFI@ARM is not available yet - VPD can be smaller (most x86 devices have only 16/8K for RO/RW) - Increase RW_LEGACY to 1M (recommended value) - Move all new saved space to CBFS BUG=b:134624821 TEST=Built Kukui image and boots on Rev2 units.
