vbe: Add an implementation of VBE-ABrec
So far only VBE-simple is implemented in U-Boot. This supports a single
image which can be updated in situ.
It is often necessary to support two images (A and B) so that the board
is not bricked if the update is interrupted or is bad.
In some cases, a non-updatable recovery image is desirable, so that the
board can be returned to a known-good state in the event of a serious
failure.
Introduce ABrec which provides these features. It supports three
independent images and the logic to select the desired one on boot.
While we are here, fix a debug message to indicate the function it
called. Provide a maintainers entry for VBE.
Note that fwupdated only supports VBE-simple so far, but supports for
ABrec will appear in time.
