x86, irq: update_mptable needs pci_routeirq



To get all device irq routing and to save them.

This is basically an implicit pci=routeirq enablement if (and on if)
the update_mptable boot option (which is off by default) has been
specified.

[ Impact: extend the update_mptable boot opion's scope ]
