vboot: Fix linking error with USE_OPTION_TABLE enabled
Fix a linking problem with VBOOT and USE_OPTION_TABLE enabled.
Make use of cbfs_locate_file_in_region() and always search the
cmos_layout.bin in the 'COREBOOT' region.
With this change applied there's no need to include the vboot_locator
in SMM any more, we can't break NVRAM with different CMOS layouts,
and we keep VBOOT and non VBOOT behaviour the same.
Only include cmos_layout.bin and cmos.default in RO region.
Add notes explaining the decisions.
Tested on Intel Sandybridge, builds and boots with vboot enabled.
