pci_present() should be killed. It's left over from 2.0 or 1.2 days,
and has no meaning anymore.

The old-kernel use was to determine if a PCI bus. Drivers had to check
if a PCI bus was present, before probing for a PCI device using the
old-old find-by-slot-and-busid method of PCI bus probing. As the
now-old method of PCI bus probing (pci_find_device) and the current PCI
API both provide correct behavior when no PCI bus is present,
pci_present() itself no longer has any meaning and is entirely redundant.

At the very least, we should use the gcc "deprecated" attribute on
pci_present definitions, both normal and no-op.

IMO pci_present should go before 2.6.0... it's lived long enough.
