[PATCHv4 4/9] Bluetooth: Add AMP-related data and structures for channel signals

[Mat Martineau <mathewm@codeaurora.org>]

AMP channel creation and channel moves are coordinated using the L2CAP
signaling channel.  These definitions cover the "create channel",
"move channel", and "move channel confirm" signals.
