f826e6efb4 crypto: hisilicon - Unify error detect process into qm
In error detect process, a lot of duplicate code can put into qm. We add
two callback(get_dev_hw_err_status and log_dev_hw_err) into struct
hisi_qm_err_ini to handle device error detect, meanwhile the qm error
detect not changed.

eaebf4c3b1 crypto: hisilicon - Unify hardware error init/uninit into QM
The initialization and uninitialization of zip/hpre/sec/qm hardware error
is processed in respective drivers, which could be unified into qm.c. We
add struct hisi_qm_err_ini into struct hisi_qm, which involve all error
handlers of device and assignment should be done in driver probe.

f2c5d27bb8 crypto: hisilicon - still no need to check return value of debugfs_create functions
Just like in 4a97bfc796 ("crypto: hisilicon - no need to check return
value of debugfs_create functions"), there still is no need to ever
check the return value.  The function can work or not, but the code
logic should never do something different based on this.

HiSilicon HPRE engine supports PCI SRIOV. This patch enable
this feature. User can enable VFs and pass through them to VM,
same HPRE driver can work in VM to provide RSA and DH algorithms
by crypto akcipher and kpp interfaces.
