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.

Fixes: a15f2c08c7 ("PCI: hv: support reporting serial number as slot information")
