xen/irq: Export 'xen_pirq_from_irq' function.
We need this to find the real Xen PIRQ value for a device
that requests an MSI or MSI-X. In the past we used
'xen_gsi_from_irq' since that function would return
an Xen PIRQ or GSI depending on the provided IRQ. Now that
we have seperated that we need to use the correct
function.
[v2: Deal with rebase on stable/irq.cleanup]
