Since these architectures were introduced when qemu-xhci was
already a thing, we never considered allowing the older
nec-xhci model as a fallback.
That said, every other architecture that defaults to USB3
allows this, so we might as well be consistent. The chances
of nec-xhci being available when qemu-xhci isn't are of
course close to zero.
