chromeos: Add option to back up VBNV CMOS into flash
This adds a new kconfig option that will back up the VBNV data
from CMOS to flash, and restore it if the CMOS data is invalid
during boot.
This allows special flags to not get lost when power is lost,
RTC reset is triggered, or CMOS is corrupted.
BUG=chrome-os-partner:47915
BRANCH=glados
TEST=manually tested on chell:
1-boot and run "enable_dev_usb_boot"
2-reboot and check that it is enabled with crossystem
3-run "mosys nvram clear"
4-reboot and check that it is still enabled
