[PATCH 1/3] x86/PCI: Show the physical address of the $PIR table

[Maciej W. Rozycki]

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
