From: Johan Hedberg <johan.hedberg@xxxxxxxxx>
This patch adds a basic skeleton for a new self-test module. The module
will be used to implement various self-tests for the bluetooth
subsystem. The first user will be SMP, for which it is of particular
importance that this is as a separate module to avoid loading priority
conflicts with the crypto subsystem and the rest of the Bluetooth
subsystem.

v2: Use tristate instead of bool in Kconfig, depend on BT_LE and improve
description.
