[SeaBIOS] [RFC] vgahooks: Add Google stumpy, lumpy, and link boards to intel vgahook list.

[Kevin O'Connor]

Add in the detection for a handful of additional boards found in the
Chromium repo.  This ports over and simplifies the code in that repo.

Signed-off-by: Kevin O'Connor

Are these boards in active distribution and is it worth having them in
the seabios main repo?
