PCI: Add Kconfig PCI_IOV dependency for PCI_REALLOC_ENABLE_AUTO

Ensure only valid Kconfig configurations for PCI_REALLOC_ENABLE_AUTO. This
is done by selecting PCI_IOV, which is required by PCI_REALLOC_ENABLE_AUTO
to work.

          Say Y here if you want the PCI core to detect if PCI resource
          re-allocation needs to be enabled. You can always use pci=realloc=on
-          or pci=realloc=off to override it.  Note this feature is a no-op
-          unless PCI_IOV support is also enabled; in that case it will

-          been allocated by the BIOS.

          When in doubt, say N.
