It'd be nice to keep all the DT nodes with a reg property together, and
sorted in reg order.

As before, I think any DT node for a HW block that may-or-may-not-be
used based on board connectivity/features should be disabled in the SoC
.dtsi file, and enabled in the board's DT file if the feature is useful
for that board.
