This fixes issues we were seeing on various models, but it seems our old hardcoded 80ųA bias current was working around a firmware bug on at least one model laptop. In order to both have our cake and eat it, this commit adds a dmi based list of models where we need to override the firmware set bias current and adds the one model we now know needs this to it: The Lenovo Ideapad 100S (11 inch version).
