crypto: hisilicon/zip - add a work_queue for zip irq

mainline inclusion
from mainline-v5.11-rc1
commit 1dc44035
category: feature
bugzilla: 173981
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1dc440355e472a60a98cb4ec9aa5ec56267a96fc



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

The patch 'irqchip/gic-v3-its: Balance initial LPI affinity across CPUs'
set the IRQ to an uncentain CPU. If an IRQ is bound to the CPU used by the
thread which is sending request, the throughput will be just half.

So allocate a 'work_queue' and set as 'WQ_UNBOUND' to do the back half work
on some different CPUS.
