mb/google/volteer: Reorganize FMAP This change reorganizes FMAP for volteer to make use of the lower 16MiB of the SPI flash for RW_SECTION_A and RW_MISC in addition to RW_LEGACY. This is now possible because TGL supports memory mapping of BIOS region greater than 16MiB. Following changes are made in chromeos.fmd as part of this: 1. Move RW_SECTION_A and RW_MISC to lower 16MiB. 2. Reduce size of RW_LEGACY to 2MiB since we longer need to use it as a placeholder in the lower half of the SPI flash. 3. Reduce size of RW_ELOG to 4KiB as coreboot does not support a larger region for ELOG. 4. Increase WP_RO to 8MiB to allow larger space for firmware screens. GBB size is thus increased to 448KiB.
