Bluetooth: Add skeleton for SMP self-tests
This patch adds a basic skeleton for SMP self-tests. The tests are put behind a new configuration option since running them will slow down the boot process. For now there are no actual tests defined but those will come in a subsequent patch. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
