After reviewing the qdrive3 schematics I do think that describing the
two ADP boards as a delta between them is not going to serve us well in
the long run - they are quite different.

So let's just create a new dts for the qdrive3, and if there are
additional boards they will either again be sufficiently different or we
could turn these into dtsi files and inherit from there.
