I think you can use memory-region here.
Isn't memory-region intended for references into the /reserved-memory
node. If so, that isn't appropriate in this case since this property
typically points at on-chip SRAM that isn't included in the OS's view of
"system RAM".
Or, should /reserved-memory be used even for (e.g. non-DRAM) memory
regions that aren't represented by the /memory/reg property?

Aren't these doxygen markup? Does that work with docbook? If not,
remove.
These headers are part of the BPMP FW release. It's preferable not to
edit them when incorporating them into the Linux kernel (or any other SW
stack) to simplify integration of any updated versions of the header, by
removing the need to edit the file when doing so. Given that, do you
still object?
