[PATCH] ideapad: let Fn+F5 also trigger KEY_BLUETOOTH

[Ike Panhc <ike.pan@canonical.com>]

The design for ideapad Fn-F5 key is not only for wifi but for all
radio device including wifi, bluetooth and wwan. Idealy it shall
acts like this:

    wifi on          wifi off         wifi on         wifi off
     bt on   ----->   bt on   ----->   bt off  ----->  bt off

This patch will switch wifi mode every key-push and switch
bluetooth mode every two key-push.
