Subject: [035/129] x86/PCI: build amd_bus.o only when CONFIG_AMD_NB=y

3.2-stable review patch.  If anyone has any objections, please let me know.

From: Bjorn Helgaas <bhelgaas@...gle.com>

commit 5cf9a4e69c1ff0ccdd1d2b7404f95c0531355274 upstream.

We only need amd_bus.o for AMD systems with PCI.  arch/x86/pci/Makefile
already depends on CONFIG_PCI=y, so this patch just adds the dependency
on CONFIG_AMD_NB.
