[PATCH 0/1][Eoan][SRU Disco] Fix additional regression in CMA/DMA rework

[dann frazier]

BugLink: https://bugs.launchpad.net/bugs/1841483

As noted in the patch, my backport drops the upstream hunk that applied to
dma-iommu.c, as it wasn't yet converted over to the new interface until
after v5.2. I wouldn't mind a 2nd set of eyes confirming this approach.
Regression tested on a HiSilicon D06.
