[PATCH 3/3] Support hardcoded Nintendo Wii Remote pins

[David Herrmann <dh.herrmann@googlemail.com>]

The Nintendo Wii Remote requires the destination bluetooth address
as pincode. This changes the pin handling by skipping the agent
module and sending an hardcoded pin if the target device is a
Nintendo Wii Remote.
