Basically the whole content of pci-thunder-ecam.c and pci-thunder-pem.c.
pci-thunder-ecam.c contains config space accessors. Similar for
pci-thunder-pem.c but it also has extra init call (it is now called
thunder_pem_init) which finds and maps related registers.
They seem to do much more than just override the accessors, they actually
change the contents of the config space as well. Is that really necessary
on ACPI based systems as well?
Another idea: how about moving all of this logic into ACPI and calling
some AML method to access the config space if the devices are that
far out of spec.
