Don't let other driver config options influence us, as it makes the
code more complex and fragile for a small benefit. There's nothing
wrong with instantiating I2C devices even if they don't have a driver.
And we're talking about 835 extra bytes in the binary on x86-64,
that's hardly worth arguing about.

I don't know if Fujitsu is ever going to produce Patsburg-based

On a side note, I'm not even sure if it is right to enable detection
