bf6a7a5ad6 crypto: hisilicon - avoid unused function warning
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.

79e09f30ee crypto: hisilicon - add SRIOV support for ZIP
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.

62c455ca85 crypto: hisilicon - add HiSilicon ZIP accelerator support
The HiSilicon ZIP accelerator implements the zlib and gzip algorithm. It
uses Hisilicon QM as the interface to the CPU.

This patch provides PCIe driver to the accelerator and registers it to
crypto acomp interface. It also uses sgl as data input/output interface.
