drivers/vpd: add VPD region VPD_RW_THEN_RO
This change is based on the concept that system user's (overwrite) settings are held in VPD_RW region, while system owner's (default) settings are held in VPD_RO region. Add VPD_RW_THEN_RO region type, so that VPD_RW region is searched first to get overwrite setting, otherwise VPD_RO region is searched to get default setting.
