 controller's wireless mode

Update on commit info: seems these controllers support Xbox mode when 
using wired mode, however, their firmware has some weird enumeration 
logic that won't work with current xpad driver(It would enum as xbox 
first if no driver is loaded, then disconnect and re-enum as NS 
controller, finally something else), and by default wired mode would end 
with nintendo driver.
