[flashrom] [PATCH] Undo all PCI writes on shutdown

[Carl-Daniel Hailfinger]

Undo all PCI config space writes on shutdown.
This means all chipset enables etc. will be undone on shutdown.
Any writes which are one-shot should use the permanent ppci_write_*
variants.

Extend the number of available register_shutdown slots to 32.
