PCI: pull pcibios_setup() up into core
Currently, all of the architectures implement their own pcibios_setup()
routine. Most of the implementations do nothing so this patch introduces
a generic (__weak) routine in the core that can be used by all
architectures as a default. If necessary, it can be overridden by
architecture-specific code.
