This patch adds battery charge control support on Fujitsu notebooks
via the S006 method of the FUJ02E3 ACPI device. With this method it's
possible to set charge_control_end_threshold between 50 and 100%.
Tested on Lifebook E5411 and Lifebook U728. Sadly I can't test this
patch on a dual battery one, but I didn't find any clue about
independent battery charge control on dual battery Fujitsu notebooks
either. And by that I mean checking the DSDT table of various Lifebook
notebooks and reverse engineering FUJ02E3.dll.
