twl4030-madc: Request processed values in twl4030_get_madc_conversion
Not setting the raw parameter in the request causes it to be randomly initialized to a value that might be different from zero or zero. This leads to values that are randomly either raw or processed, making it very difficult to make reliable use of the values.
