Personally, I don't like this "i2c-bridge" flag either, but for a different
reason - i2c-bridge makes it sound like it's doing something it's not.

What it is doing is as you stated in the cover - it's an offload mechanism,
just like if it were possible to use DMA to supply the data to the I2C
interface.

I think Maxime is correct - this should be identified by a variation in
the compatible string, not by a flag in DT.
