siemens/mc_apl1: Fix accuracy issue with IDT PMIC
Due to an accuracy issue on IMON in the IDT PMIC, the reported system power consumption was higher than the actual consumption. To prevent this problem, a logic must be implemented in mainboard_init(). This logic consists of slope and offset as constants for Vcc and Vnn, which need to be programmed by coreboot. This fix compensates for the accuracy issue.
