crypto: hisilicon/qm - stop function and write data to memory

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I7AUVE


CVE: NA

----------------------------------------------------------------------

Before the system is shutdown, the accelerator driver
needs to stop the device and write data to the memory.
This prevents the accelerator from accessing addresses
and writing data to the memory after the memory is reclaimed
by the system, causing device exceptions and generating NFE errors.
