    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.
