It seems like V1 and V2 basically don't share any code at all, so it seems
like they should be separate drivers.  And for V1 it seems like it might
even be better off as a blk-mq driver - which could then reuse the DAC960
name and device nodes?

For the V2 firmware your approach looks great, though.
