I nearly missed this. This is a userspace header for a reason. The ABI is
fixed so we can't change the enumeration. We can only add to the end.
Good thing the discussion on the _ came up and made me wonder why the name
above was in near one with underscores!

> IIO_MOD_NORTH_MAGN,
All userspace code using these would now be broken.
