For ARM this creates a problem where we use the in-kernel IRQ chip before having fully initialized it. But with the new kernel interface we cannot finish the GIC initialization before we know the number of used IRQs, so we have to wait until all devices have been created and initialized. Since the in-kernel GIC emulation resets the IRQ line anyway and also QEMU gets away without resetting it, the easiest solution is to drop the IRQ line reset.
