Bluetooth: hci_core: Rework hci_conn_params flags
This reworks hci_conn_params flags to use bitmap_* helpers and add support for setting the supported flags in hdev->conn_flags so it can easily be accessed. Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
