power: supply: mm8013: Add more properties

While scanning the internet for MM8013 PDFs, I found one for a different
IC from Mitsumi, MM8118 at [1]. It turned out however, that when you
search through the PDF, the MM8118 text has an invsible text layer
containing "MM8013" underneath..

With some elbow grease, I was able to confirm that most of the registers
match between the two ICs. Based on that finding, introduce live battery
voltage readout, hw-decided charge behavior readout and max current
readout. Also, expand the existing POWER_SUPPLY_HEALTH reporting.
