I think we should rename our hook from “raspi3-firmware” to
“50raspi3-firmware”. update-initramfs uses run-parts(8) to invoke hooks, so
you could then ship a hook with a higher number which would be guaranteed
to run after the raspi3-firmware hook.

Let me know if that sounds good, and I’ll prepare a package upload.
