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
- automatically re-allocate PCI resources if SR-IOV BARs have not
- been allocated by the BIOS.

When in doubt, say N.
