PCI: add a PCI resource reallocation config option
Add a new config option, PCI_REALLOC_ENABLE_AUTO, which will
automatically try to re-allocate PCI resources if PCI_IOV support is
enabled and the SR-IOV resources are unassigned. Behavior can still be
controlled using the pci=realloc= parameter.
-v2: According to Jesse, adding one CONFIG option for distribution to
disable it or enable it.
-v3: update Kconfig text (jbarnes)
