The combination of 'vexpress-a9' and kernel_irqchip=on
don't make any sense -- the former implies "not using
KVM" because KVM needs an A15 guest CPU, whereas the
latter implies "using KVM". In any case kernel_irqchip=on
is the default when using KVM.
You can just delete the kernel_irqchip option.

You might want to consider -M vexpress-a15, if you
want a setup that will let you use KVM (will probably
need to reconfig your kernel appropriately; may
need to discard "earlyprintk" if you compiled the
kernel with the dodgy "guess earlyprintk serial port
address based on exact revision-and-patchlevel of CPU"
option.)
