mb/google/rex: Add new FMD for prod (QS) Meteor Lake silicon
Intel Meteor Lake QS silicon provides better size optimized pre-x86 reset blobs. This patch creates a new flash layout (FMD) for QS to accommodate those optimizations, and renames the existing FMD for ES (pre-prod) silicon. Comparative analysis between QS and ES flash layout is here: For QS silicon: - SI_ALL reduced from 9MB to 8MB. - SI_BIOS increased by 1MB (from 23MB to 24MB) to fill in the 32MB SPI layout. - ME_RW_A/B reduce from ~4.5MB to 4MB. - Ensure RW-B slot is starting at 16MB boundary. - Unused space increased by 1MB. For ES silicon: - SI_ALL: 9MB - SI_BIOS: 23MB - ME_RWA/B: 4.5MB (for ISH) and 4.4MB (non-ISH). - Unused space 3MB (for release) and 2MB (for debug) layout.
