Add led support, using generic led class. Thomas Tuttle's patch <http://lkml.org/lkml/2006/7/6/247> was very usefull. We use hotk->status to store led status because it's very hard to find acpi method to get the right status... To reduce the code, I use a lot of macro (ASUS_LED, ASUS_LED_REGISTER, etc ...), because the code is the same for all leds ...
