If this would usually go via arm-soc, feel free to take it via this
route. I'll drop the patch from my tree.

I can't see why the TRM would be wrong. This is actually consistent with
the expected practice of aligning all devices on a 64kB boundary and
size so that you don't get any nasty surprise when passing the device to
a VM (*cough* GIC400 *cough*).
Robin, any chance you could check this?
