i2c-i801: Don't depend on other kernel driver config options
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.
