fujitsu-laptop: Add BL power, LED control and radio state information
The FUNC interface in the Fujitsu-Siemens DSDT was unused until now. It exposes state information that is now reported in additional platform files (whether the radios are killed by the hardware switch or operational, whether the machine is docked and whether the lid is open). Support for the backlight class is now extended with the ability to power the backlight on & off. Optional support for the LED class allows the keyboard headlamps found on the U810 netbook and the Fujitsu logo illumination on the P8010 notebook to be turned on & off. This was fed through checkpatch.pl and tested on the S6420, P8010 & U810 platforms.
