Input: i8042 - add Dritek keyboard extension quirk 



Some Wistron based laptops need us to explicitly enable the 'Dritek
keyboard extension' to make their extra keys start generating scancodes.
Originally, this was just confined to older laptops, but a few Acer
laptops have turned up in 2007 that also need this again.
