staging:iio:mag:hmc5843 fix incorrect endianness of channel as a result of missuse of the IIO_ST macro.
This driver sets the shift value equal to IIO_BE (or 1) rather than setting
that to 0 and specificying the endianness. This means the channel type is
missreported as
[be|le]:u16/16>>1 where the be|le is dependent on the cpu native endianness,
rather than
be:u16/16>>0 resulting in any userspace code using this information, miss
converting the channel and generating thoroughly trashed data.
