I think this is also an issue with the following other drivers.  They all
set the handler to something that uses an IRQ domain before they
actually initialize the domain:
Yes, I agreed with your assessment and also noticed that others drivers have
similar issues. I just don't have any of those platforms to try to reproduce
the bugs and test a fix.
Even if you don't have other platforms for testing, I'm thrilled when
folks point out issues with them and (given time and inclination) post
patches for them.

I'd much rather fix *all* instances of the problem than just one, even
if we can't test them all.  Frequently driver maintainers will review
and test patches for their hardware even if we can't.
Ok. I'll try to make some time next week to look at these drivers then
and post at least RFC/RFT patches for people with available hardware to
test the changes.
