staging:iio: Fix adis16240 channel offsets and scales
Most of the channel offsets and scales in the adis16240 are incorrect: * Temperature scale is of by a factor of 1000 * Voltage scale is of by a factor of 1000 * Temperature offset is completely wrong * Peak scale is completely wrong This patch fixes these issues. Also use the IIO_G_TO_M_S_2 macro for the acceleration scale since this makes it much easier to compare it to the value given in the datasheet.
