vboot: Add support for OPROM_MATTERS and SLOW_EC
In order to display a "update in progress" screen on devices with a slow EC or PD chip it may be necessary to also load the VGA Option ROM when doing EC software sync. This adds config options for VBOOT_EC_SLOW_UPDATE which simply sets a flag in the input parameters that is already handled by vboot. It also adds a config option for VBOOT_OPROM_MATTERS which is a bit more tricky in that it sets a flag in input parameters, but also needs to keep track of the option rom being loaded and pass that flag into VbInit as well. Since VbInit will clear the NV bit for option rom loaded the check that is done in vboot_wants_oprom() needs to first compare against the vboot handoff copy of the input flags. BUG=chrome-os-partner:32379 BRANCH=samus TEST=manual testing: 1) in normal mode, with EC/PD in RW, ensure that they are rebooted to RO and the VGA Option ROM is loaded and the wait screen is displayed, and then the system is rebooted at the end and the VGA Option ROM is not loaded. 2) same as #1 with EC/PD in RO already, same result 3) same as #1 with system in developer mode, same result except there is no reboot at the end of software sync 4) same as #1 with system in developer mode and EC/PD in RO, ensure that there is no extra reboot at the beginning or end of software sync.
