It seems most if not all Allwinner based tablets use the reference design
Allwinner provides. The design specifies how components are connected,
what models could be used, etc.. Maybe we could rename sun*i-q8-common to
sun*i-reference-design and use that? We'd still have board.dts files
including it, and providing the board name.
