mb/lenovo/*: Add support for VBOOT on 12MiB devices
Enable VBOOT support on all devices that have a 12 MiB flash, using
RW_MAIN_A + RW_MAIN_B partition, allowing the use of tianocore payload
in both RW_MAIN_A, RW_MAIN_B and WP_RO.
* Add VBNV section to cmos.layout
* Add FMAP for VBOOT
* Select Kconfigs for VBOOT
* Enable VBOOT_SLOTS_RW_AB by default
The VBNV is intentionally not covered by the CMOS checksum.
Tested on x230 and T440p.
