BookE also wants to support level based interrupts, so let's implement all the necessary logic there. We need to trick a bit here because the irqprios are 1:1 assigned to architecture defined values. But since there is some space left there, we can just pick a random one and move it later on - it's internal anyways. Signed-off-by: Alexander Graf <agraf@suse.de>
