Even though axp20x-i2c seems to be the only "DT only" i2c client,
would it make sense to add DT-based module autoloading to the i2c
core?

This also made me realize we probably don't have module auto-loading
for sunxi-rsb either.

Both should be doable with Stephen Boyd's "of: device: Export
of_device_{get_modalias, uvent_modalias} to modules" patch.
