extmod/btstack: Update BTstack bindings to work with latest BTstack.
The following multi-tests pass (eg with PYBD_SF6+LEGO_HUB_NO6): ble_gap_advertise.py ble_gap_connect.py ble_gap_device_name.py ble_gattc_discover_services.py ble_gatt_data_transfer.py perf_gatt_char_write.py perf_gatt_notify.py stress_log_filesystem.py These are the same tests that passed prior to this BTstack update. Also tested on the unix port using H4 transport. Signed-off-by: Damien George <damien@micropython.org>
