I simply failed to describe the issue.

As of today, the MCQ code refers to the region that our bindings call
"std" by the name "ufs_mem" (which this patch fixes).
Totally same thing in hardware, but it would obviously not work without
DT changes (which would be rightfully rejected as there is no reason to
change the name).
