staging: iio: remove now defunct header definitions and add some statics
Now we have combined all chrdevs into one, some bits and bobs are only needed in industrialio-core.c and don't need to be in the core header. Also remove some unused defines. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
