iio: adc: MCP3564: fix calib_bias and calib_scale range checks

The current implementation uses the AND (&&) operator to check if the
value to write for IIO_CHAN_INFO_CALIBBIAS and IIO_CHAN_INFO_CALIBSCALE
is within the valid ranges.
The evaluated values are the lower and upper limits of the ranges,
so this operation always evaluates to false.

The OR (||) operator must be used instead.
