UFS controllers may be cache coherent and must be marked as such in the
devicetree to avoid data corruption.
This is specifically needed on recent Qualcomm platforms like SC8280XP.

James and Martin,
I'm resending as reminder in case you missed the first submission which
included an arm64 dts update and also did not have you on CC as I was
following scripts/get_maintainer.pl too literally:
https://lore.kernel.org/all/[email protected]/
I've added Rob and Bjorn's Reviewed-by tags from the above thread.
Could you take this one through the scsi tree?
Johan
