Hmm, qpic nand is not there only on C3 and available in rest
of dk04-c* variants. So it should work, downstream also
does it in same way. Anyways, from a readability point, feel that
better to make these uncommon configurations in each board file
specifically rather than putting in common file and changing like this.
