crypto: hisilicon/qm - add stop queue by hardware

mainline inclusion
from mainline-v5.13-rc1
commit 7ed83901
category: feature
bugzilla: 173981
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7ed83901326f781524af2d969185440efe23f964



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

Kunpeng930 could be able to stop queue by writing hardware registers,
which will trigger tasks in device to be flushed out.

In order to be compatible with the kunpeng920 driver, add 'qm_hw_ops_v3' to
adapt Kunpeng930. And 'stop_qp' callback is added in 'qm_hw_ops_v3' to
write hardware registers. Call 'stop_qp' to drain the tasks in device
before releasing queue.
