iio: Move callback buffer to its own module
Currently the IIO callback buffer implementation is directly built into the IIO core module when enabled. Given that the callback buffer module is standalone functionallity there is really no reason to do this. So move it to its own module. Also rename the source to follow the standard IIO module naming convention as well as add a license notice to the file.

Should be selected by any drivers that do in-kernel push
usage. That is, those where the data is pushed to the consumer.
