If they exist on in the design, then enabling them is fine.

The distinction I've gone with is it doesn't make sense to have them
enabled when the i2c pads on the SoC are not broken out, or if they're
only connected to ground, so there's no way of them ever "working".

I'm happy with the dt as is it is. If you're happy then I will merge.
