This pull requests supersedes the previous pull request for v4.21, which didn't
make it.

It's unchanged from the previous pull request, just rebased on top of v5.0-rc1.

The "dma-direct: provide a generic implementation of DMA_ATTR_NON_CONSISTENT"
discussion is about future work to help with cases like this, so this doesn't
block merging this PR.
