vboot: Add a reboot option to keep EFS in RO with the AP off.
With EFS, the EC will typically switch to RW shortly after boot.
cros_ec_softrec_power triggers recovery mode using the hostevent console
command after rebooting the EC with ap-off and then simulates a power
button press. This requires the EC to remain in RO after rebooting so
doesn't currently work with EFS.
Add a reboot option "ap-off-in-ro" to request the EC remain in RO with
the AP off after rebooting.
