Revert PCI config space writes on shutdown
This means all chipset enables etc. will be undone on shutdown.
Reversible PCI config space writes now use rpci_write_*().
PCI config space writes which are one-shot (e.g. communication via
config space) should continue to use the permanent pci_write_*
variants.
Extend the number of available register_shutdown slots to 32.
Corresponding to flashrom svn r1232.
