vboot: Disable VBNV_OPROM_NEEDED after successful update
The VBOOT_OPROM_NEEDED flag is used for EC software sync when the
VBSD_EC_SLOW_UPDATE flag is set.
After a successful EC software sync vboot requests a reboot to disable
graphics but it is not clearing the VBNV flag first. With vboot1 this
was getting cleared as a side effect of calling VbInit in normal mode.
BUG=chrome-os-partner:49560
BRANCH=glados
TEST=Enable EC_SLOW_UPDATE on chell and test EC software sync in normal
mode and ensure that it reboots and does not do graphics init if the
update is successful.
