Subject: [PATCH] PCI: Move prototypes for pci_bus_find_capability to
 include/linux/pci.h

We need pci_bus_find_capability() in some arch/powerpc code so move
the prototype into a header accessible to it.

Also kill the duplicate prototype for pci_bus_alloc_resource().

Signed-off-by: Kumar Gala <galak@...nel.crashing.org>

Here's a version that just moves the prototype I need for arch/powerpc and
kills the duplicate.
