Subject: [PATCH 1/2] iio: magnetometer: als31300: remove unused
 IIO_CHAN_INFO_PROCESSED handling

The als31300 driver does not advertise IIO_CHAN_INFO_PROCESSED in its
info_mask_* fields, so the corresponding case in read_raw() is never used.
Drop the dead code to reduce unnecessary branches and improve clarity.
