    x86/PCI: Show the physical address of the $PIR table

    It makes no sense to hide the address of the $PIR table in a debug dump:

    PCI: Interrupt Routing Table found at 0x(ptrval)

    let alone print its virtual address, given that this is a BIOS entity at
    a fixed location in the system's memory map. Show the physical address
    instead then, e.g.:

    PCI: Interrupt Routing Table found at 0xfde10
