The user only needs to extract a short string from the chip name instead of looking up the chip in the datasheet, understand the nomenclature, extract the measurement range and then convert all units to pascals. New feature: - SPI compatibility for Honeywell MPR sensors that require it. Both binding and driver are backwards compatible. Tested in I2C and SPI modes with two different sensors. The refactor requires property function present in the togreg branch.
