The node is empty for now. It is needed to allow other DT snippets
to add thermal zone entries.

Others can feel free to disagree, but IMO ${SUBJECT} patch is not
needed.  Instead patch #3 in your series should just define a
"thermal-zones" node at the root level.  The "thermal-zones" node is a
well-defined node with a well-defined node name and location (see the
"thermal.txt" binding).  If the SoC has a "thermal-zones" node and so
does the PMIC then they'll just be merged.

Just defining it here makes perfect sense, thanks!
