Bug description:
SRU Justification
=================
[Impact]
* Users with HiSilicon Security Engine (SEC) version 2 controller fail to
allocate Uacce.
[Fix]
* upstream 183b60e005975d3c84c22199ca64a9221e620fb6 crypto: hisilicon/qm -
modify the uacce mode check
[Test Plan]
* Deploy Ubuntu Focal with HWE 5.13 kernel to a Kunpeng920 chip with
HiSilicon Security Engine (SEC) version 2 controller
* Boot the system
* 'dmesg | grep "fail to alloc uacce"' and you will see complains from
hisi_sec2. For example: [ 27.015484] hisi_sec2 0000:b6:00.0: fail to alloc
uacce (-22)
[Where problems could occur]
* The regression can be considered as low, since it is HiSilicon crypto
system specific

crypto: hisilicon - add ZIP device using mode parameter
Add 'uacce_mode' parameter for ZIP, which can be set as 0(default) or 1.
'0' means ZIP is only registered to kernel crypto, and '1' means it's
registered to both kernel crypto and UACCE.
