Browse source 
Tell twl4030_madc_conversion that this driver needs raw values.
Driver twl4030_madc has some hardcoded values and conversation
functions which are incorrect for Nokia RX-51 board. This driver
rx51_battery expects raw values which convert itself.

This patch fixing values reported by power supply interface.
