ACPI: move models with win8 brightness problems from win8 blacklist to use_native_backlight
When the windows8 related backlight problems became evident, 2 approaches were follow in parallel, one was to stop claiming to be windows 8 / 2012, the other was to tell acpi_video to stop registering a backlight driver. I've read all the threads and it seems that which approach ended up being applied to which model laptop was never really a concious decision (AFAIK): https://bugzilla.kernel.org/show_bug.cgi?id=51231 https://bugzilla.kernel.org/show_bug.cgi?id=60682 So lets move all the models which are only on the win8 blacklist because of brightness issues to the use_native_backlight list, which is the smaller hammer to use to solve the backlight issues. Making this change is esp. attractive now that 3.16 has video.use_native_brightness=1 by default. If that new default does not get reverted because of regressions, then we can drop all the models with a use_native_backlight quirk, greatly reducing the number of models we've a quirk for.
