Calibration data for it was placed outside of the main calibration data blob, so it is not accessible by the current blob-parsing code. Moreover data for the sensor's p2 is not contiguous in the fuses. This makes it hard to use nvmem_cell API to parse calibration data in a generic way. Since the sensor doesn't seem to be actually used by the existing hardware, disable the sensor for now.
