Bug description:
[Impact]
Setup soft RAID5 on kunpeng920 machine and system will crash because of hisi_dma timeout. This issue can be reproduced with all Ubuntu kernel with hisi_dma.

[Test Plan]
Setup soft RAID5 and wait for few seconds. Kernel will crash.

[Regression Risk]
CONFIG_HISI_DMA only affects kunpeng920 platform. Minimal risk for other platform, and full regression test is needed on kunpeng920.
