powerpc: Add virq_is_host to reduce virq_to_host usage
Some irq_host implementations are using virq_to_host to check if
they are the irq_host for a virtual irq. To allow us to make space
versus time tradeoffs, replace this usage with an assertive
virq_is_host that confirms or denies the irq is associated with the
given irq_host.
