mb/google/rex: Update Flash Layout to fit WP_RO within 4MB
This patch updates the Rex flash layout to optimize WP_RO to 4MB.
The idea is to create more space inside FW_RW_A/B to accommodate
multiple blobs to boot google/rex with different Intel MTL SoC stepping.
Changes for chromeos.fmd:
SI_BIOS:
RW_SECTION_A/B: Reduce to 7MB.
RW_LEGACY: Reduce to 1MB.
RW_MISC: Increased to 1MB.
RW_UNUSED: 3MB (reserved)
WP_RO: Reduce to 4MB
Additionally, ensure RW_SECTION_B region starts at 16MB boundary in the
SPI Flash.
BUG=b:277143384
TEST=Able to build and boot google/rex with FSP release and debug image.
