This because DES library has been moved to lib/crypto in this commit
'04007b0e6cbb ("crypto: des - split off DES library from generic DES cipher driver")'.
Fix this by selecting CRYPTO_LIB_DES in CRYPTO_DEV_HISI_SEC.
Fixes: 04007b0e6c ("crypto: des - split off DES library from generic DES cipher driver")
Fixes: 894b68d8be ("crypto: hisilicon/des - switch to new verification routines")

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.

HiSilicon accelerators in Hip08 use same hardware scatterlist for data format.
We support it in this module.
Specific accelerator drivers can use hisi_acc_create_sgl_pool to allocate
hardware SGLs ahead. Then use hisi_acc_sg_buf_map_to_hw_sgl to get one
hardware SGL and pass related information to hardware SGL.
The DMA address of mapped hardware SGL can be passed to SGL src/dst field
in QM SQE.

QM is a general IP used by HiSilicon accelerators. It provides a general
PCIe interface for the CPU and the accelerator to share a group of queues.
A QM integrated in an accelerator provides queue management service.
Queues can be assigned to PF and VFs, and queues can be controlled by
unified mailboxes and doorbells. Specific task request are descripted by
specific description buffer, which will be controlled and pass to related
accelerator IP by QM.
This patch adds a QM driver used by the accelerator driver to access
the QM hardware.

This accelerator is found inside hisilicon hip06 and hip07 SoCs.
Each instance provides a number of queues which feed a different number of
backend acceleration units.
The queues are operating in an out of order mode in the interests of
throughput. The silicon does not do tracking of dependencies between
multiple 'messages' or update of the IVs as appropriate for training.
Hence where relevant we need to do this in software.
