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.
