iio: accel: bmc150: Fix bma222 scale unit
commit 6e2a90a upstream. According to sysfs-bus-iio documentation the unit for accelerometer values after applying scale/offset should be m/s^2, not g, which explains why the scale values for the other variants in bmc150-accel do not match exactly the values given in the datasheet. To get the correct values, we need to multiply the BMA222 scale values by g = 9.80665 m/s^2.
