This chip uses a offset register in page1, which is added to the current register to give the user the current measurement. If this value is wrong, the user will get an offset current value, even if the current is zero, for instance. This patch gives support for reading the page1 registers (including the offset register) and for writing to the offset register. The DS2438 datasheet shows a calibration routine, and with this patch, the user can do this quickly by writing the correct value to the offset register. This patch was tested on real hardware using a power supply and an electronic load.

Hello! Thanks for the review! I'm sorry about this again, I did it for my patches but forgot the cover letter. Won't repeat!
