[efi] Standardise PCI debug messages 

Use the PCI bus:dev.fn address in debug messages, falling back to the
EFI handle name only if we do not yet have enough information to
determine the bus:dev.fn address.

Include the vendor and device IDs in debug messages when no suitable
driver is found, to match the diagnostics available in a BIOS
environment.
