[PATCH] PCI: drivers/pci: some cleanups

This patch contains the following cleanups:
- hotplug/pciehp_core.c: make the needlessly global hpdriver_context
                         static
- #if 0 the following unused functions:
  - pci.c: pci_bus_max_busnr()
  - pci.c: pci_max_busnr()
  - proc.c: pci_proc_attach_bus()
  - remove.c: pci_remove_device_safe
