PCI: pci-hyperv: Fix build errors on non-SYSFS config
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.

PCI devices from a PCI backend to support PCI driver domains.
