Here too you should say something about why this won't break any systems
booting using an older devicetree. Specifically, the QUSB2 PHY interrupt
has never been armed on any system running mainline as those bits never
made it upstream.
So an alternative to this could also be to just drop the QUSB2 PHY
interrupt handling from this driver for now.
