vboot: copy data structures to CBMEM for downstream use
For platforms that do not employ VBOOT_STARTS_IN_ROMSTAGE, vboot verification occurs before CBMEM is brought online. In order to make vboot data structures available downstream, copy vb2_working_data from CAR/SRAM into CBMEM when CBMEM comes online. Create VBOOT_MIGRATE_WORKING_DATA config option to toggle this functionality.
