staging:iio:cdc:ad7150: Shift the _raw readings by 4 bits.
Every other register related to raw value on the datasheet is
described as correpsonding to the 12MSB of the actual
data registers + the bottom 4 bits are 0. So lets treat this
as what it actually is, which is a 12 bit value.
Note that we will have to be a little careful to compensate for
the offset and scale values.
