My rationale for my original request was that the meaning of the second
memory region is modified by this series. Previously it was always
"firmware image sections", but now it can also be "IPC resources".
Nothing changed in terms of the number of memory regions (it was 2-8
before and 2-8 after), so without making memory-region-names mandatory,
there'd be no way to tell which of the two configurations are being
used.

This patch should likely be squashed with the patch adding
memory-region-names, so that it is easily to provide an explanation for
what's going on.
