Subject: [PATCH] iio:magnetometer: Remove duplications in iio_chan_spec
The magn_3d_channels array has multiple declarations of iio_chan_spec.
Most of the iio_chan_spec are very similar, changing only by the .type
and .channel2 field. This patch reduces the code duplication by adding a
macro that can replace the iio_chan_spec repetitions in the
magn_3d_channels array.
