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
