BugLink: https://bugs.launchpad.net/kunpeng920/+bug/1933301

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
