Do you have an example of where you'd actually benefit from this?
I'd think most things could either be done reasonably well with
what's built into DTC (see what we've done in
arch/powerpc/boot/dts/fsl), or would need math expression support in
DTC (or has that been added?).

The constant example is the magic numbers we need to embed into DTs for
things like interrupt modes, making them human readable would be a real
win.
