[ Upstream commit f58ba5e3f6863ea4486952698898848a6db726c2 ]
Fix build errors when building almost-allmodconfig but with SYSFS not set (not enabled). Fixes these build errors:
ERROR: "pci_destroy_slot" [drivers/pci/controller/pci-hyperv.ko] undefined! ERROR: "pci_create_slot" [drivers/pci/controller/pci-hyperv.ko] undefined!
drivers/pci/slot.o is only built when SYSFS is enabled, so pci-hyperv.o has an implicit dependency on SYSFS. Make that explicit.
Also, depending on X86 && X86_64 is not needed, so just change that to depend on X86_64.
