FWIW, I have checked that in the meantime. The warning happens since commit
53c6d854be4e ("dt-bindings: usb: dwc3: Clean up hs_phy_irq in binding").
Reverting that eliminates the warning.

Sorry, it is my fault. I should have noticed that pattern based on the other dts
files. Nevertheless, I can send a v2 or a follow-up patch to fix the ordering so
we can avoid having a bad example in the tree.
