UPSTREAM: it8212: restore ROM BAR decode state explicitly
Instead of using reversible write (rpci_write_long) that relies on
global state, do it manually. Save original PCI config space
register contents to programmer's structure during initialization
and restore it in programmer's shutdown.
TOPIC=reduce_global_pci_state
