Oh right, I guess I did drop the addition of that label when I dropped 
that node.

The board DT could doesn't necessarily require a label though; it could 
just repeat the node name:

/ {
     i2s at 7e203000 {
         ... extra properties

Still, it looks like we typically use labels to reference nodes in 
bcm2835-*.dts, so adding the label would indeed be a good idea.
