[PATCH 07/10] Bluetooth: Add flags and setting for Secure Connections support

[Marcel Holtmann <marcel@holtmann.org>]

The MGMT_SETTING_SECURE_CONN setting is used to track the support and
status for Secure Connections from the management interface. For HCI
based tracking HCI_SC_ENABLED flag is used.
