[Impact]
The Hi1620 SoC has an onboard zip accelerator that is currently not supported by Ubuntu.

[Test Case]
ubuntu@scobee:~$ dmesg | grep zip

[ 29.697720] hisi_zip 0000:b5:00.0: enabling device (0000 -> 0002)
ubuntu@scobee:~$ lspci | grep ZIP
75:00.0 Processing accelerators: Huawei Technologies Co., Ltd. HiSilicon ZIP Engine (rev 21)
