2020-08-21crypto: hisilicon/qm - fix the process of register algorithms to cryptoYang Shen
When the devices are removed or not existing, the corresponding algorithms which are registered by 'hisi-zip' driver can't be used. Move 'hisi_zip_register_to_crypto' from 'hisi_zip_init' to 'hisi_zip_probe'. The algorithms will be registered to crypto only when there is device bind on the driver. And when the devices are removed, the algorithms will be unregistered. In the previous process, the function 'xxx_register_to_crypto' need a lock and a static variable to judge if the registration is the first time. Move this action into the function 'hisi_qm_alg_register'. Each device will call 'hisi_qm_alg_register' to add itself to qm list in probe process and registering algs when the qm list is empty.
