iio: pressure: bmp280: Simplify bmp280 calibration data reading
On bmp280 and bme280, the temperature and pressure calibration parameters
are available on a contiguous memory region. Considering this arrangement,
simplified the calibration reading function by using only one buffer
to read in batch temperature and pressure registers.
