crypto: hisilicon - remove unused and non-public APIs for qm and sec

- sec_register_to_crypto() and sec_unregister_from_crypto()
have been removed, the function declarations have not been
removed. Remove them.
- hisi_qm_start_qp and hisi_qm_stop_qp are called internally by the
QM. Therefore, the EXPORT_SYMBOL_GPL declaration of these
non-public interfaces is deleted.
