It turns out I got a very quick answer from our legal department. The
joy of filing a bug right before their scheduled meeting! We're fine
either:

a) Sending the files direct to you with an MIT license (we'd send a copy
of the last version only touched by me, un less Geert also ack's the
license change).

b) Sending a patch to convert these files to just MIT (preferable), or
perhaps dual GPLv2/MIT if that's what the kernel maintainers want.

Let me know which option works best for you.

That said, have you thought about all the other files you'll likely
need; those two IRQ related files are unlikely to be the only files that
are useful. Don't you want/need to relicense "everything" in include/dt/
and arch/*/boot/dts/?
