PCI: Remove unused ID-Based Ordering support
My philosophy is unused code is dead code. And dead code is subject to bit
rot and is a likely source of bugs. Use it or lose it.
This reverts b48d4425b602 ("PCI: add ID-based ordering enable/disable
support"), removing these interfaces:
pci_enable_ido()
pci_disable_ido()
[bhelgaas: split to separate patch, also remove prototypes from pci.h]
