mb/google/rex: Create 64MB AP Firmware binary for Proto 0
This patch provides a mitigation path for having different size SPINOR
parts across Rex board revisions. Rex Proto 0 only has 64MB SPINOR
mounted on the board, and the plan is to use 32MB later with Proto 1
onwards.
Hence, the idea here is to maintain a 32MB SPI Flash layout across all
Rex board revisions, but the Proto 0 build only selects
BOARD_ROMSIZE_KB_65536 config for adding padding at the end of the
32MB range.
BUG=b:242825380
TEST=Able to create 64MB AP Firmware for Rex with below layout:
SI_ALL: 0-9MB
SI_BIOS: 9MB-32MB
Padding/Unused: 32MB-64MB
Additionally, able to hit CPU reset on MTLRVP (has 64MB SPINOR) with
Rex AP Firmware binary.
