platform/x86: fujitsu-laptop: use brightness_set_blocking for LED-setting callbacks
All LED-setting functions in fujitsu-laptop are currently assigned to the brightness_set callback, which is incorrect because they can sleep (due to their use of call_fext_func(), which in turn issues ACPI calls) and the documentation (in include/linux/leds.h) clearly states they must not. Assign them to brightness_set_blocking instead and change them to match the expected function prototype. This change makes it possible to use Fujitsu-specific LEDs with "heavy" triggers, like disk-activity or phy0rx.
