Encapsulate hisi_qm_alloc_qps_node() to new interface to replace
find_zip_device(), which will fix the bug of creating QP failure
especially in multi-thread scenario.

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.

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.

Currently the VF can be enabled only through sysfs interface
after module loaded, but this also needs to be done when the
module loaded in some scenarios.
This patch adds module param vfs_num, adds hisi_zip_sriov_enable()
in probe, and also adjusts the position of probe.

Currently find_zip_device() finds zip device which has the min NUMA
distance with current CPU.
This patch modifies find_zip_device to return sub-optimal device when best
device has no qps. This patch sorts all devices by NUMA distance, then
finds the best zip device which has free qp.

Tiny fix to make QM/ZIP error callback print clear and right. If one version
hardware does not support error handling, we directly print this.
And QM is embedded in ZIP, we can use ZIP print only, so remove unnecessary
QM print.

The only caller of hisi_zip_vf_q_assign() is hidden in an #ifdef,
so the function causes a warning when CONFIG_PCI_IOV is disabled:
drivers/crypto/hisilicon/zip/zip_main.c:740:12: error: unused function 'hisi_zip_vf_q_assign' [-Werror,-Wunused-function]
Replace the #ifdef with an IS_ENABLED() check that leads to the
function being dropped based on the configuration.

HiSilicon ZIP engine supports PCI SRIOV. This patch enable this feature.
User can enable VFs and pass through them to VM, same ZIP driver can work
in VM to provide ZLIB and GZIP algorithm by crypto acomp interface.
