This last interrupt must be Hypervisor physical irq(10) and 12 is Hyp virtual irq, so please change it to 10. I guess you got this from downstream but it's not right and they don't boot kernel in EL2.
Does non-CrOS 8550 FW allow Linux to boot in EL2?


Sadly no, which is why this entry always gets wrong downstream.

Thanks,
