vboot: add and rejuggle Kconfig options

The ChromeOS machines employing vboot verfication require
    different combinations of support:

1. When vboot verification starts.
    2. Is the vboot code a separate stage or program?
    3. If a separate stage, does the that vboot program (verstage) return
       to the stage that loaded the verstage?

For the above, #1 is dependent on when to load/run vboot logic which
    is orthogonal to #2. However, #3 is dependent on #2. The logic
    to act on the combinations follows in subsequent patches.
