First, these are device definitions and gpio set callbacks and
shouldn't take much
of space. So, perhaps these all could be built upon single I2C support
selection.

Second, if we must build them conditionally, how about having all in
one file with
each device's definition and callback surrounded by corresponding ifdef ?
That would alteast save us file-count.
