    google/oak: Add derivative board Elm
    
    This patch adds a new mainboard Google/Elm as a derivative of
    Google/Oak, using the same code sharing technique for derivative boards
    that was pioneered with Google/Veyron*. For now, there are no
    firmware-relevant fundamental differences between the two boards.
    
    In addition, introduce a board-specific Kconfig for the "board ID
    adjustment" to represent the fact that the Elm board ID space mirrors
    the Oak board ID space with an offset of 6, meaning Elm rev0 is
    equivalent to Oak rev6, and future board changes will be made on both
    boards to maintain this stride (at least virtually... not all of those
    revisions will necessarily get built). This should make it much easier
    to keep the code that handles revision differences somewhat clean.
    (That's the theory, anyway... whether it will work out remains to be
    seen.)
    
    BRANCH=None
    BUG=None
    TEST=Booted Elm image with hardcoded board ID 0 on Oak rev6.
