accelerometer: Fix LIS2DW and MPU9250 abnormal reading

[Neko-vecter]

Fix abnormal reading when using ACCELEROMETER_QUERY and MEASURE_AXES_NOISE.

Below is what happen after commit 43ce7c0b9ad4f30277c10b086b86a0937dbfebbc. The ACCELEROMETER_QUERY and MEASURE_AXES_NOISE reading are abnormal. It around 7 times larger than normal value.

line 40 in lis2dw.py

        self.axes_map = adxl345.read_axes_map(config)

The LIS2DW and MCP9250 are using the ADXL345 SCALE value.

After change self.axes_map using the LIS2DW SCALE value.

        am = {'x': (0, SCALE), 'y': (1, SCALE), 'z': (2, SCALE),
              '-x': (0, -SCALE), '-y': (1, -SCALE), '-z': (2, -SCALE)}
        axes_map = config.getlist('axes_map', ('x','y','z'), count=3)
        if any([a not in am for a in axes_map]):
            raise config.error("Invalid lis2dw axes_map parameter")
        self.axes_map = [am[a.strip()] for a in axes_map]

Below is the result after using LIS2DW SCALE value.

Thanks. Good catch. I implemented a slightly different fix (commit d8d072b3).
