Indexing the OperationRegion with a single field fixes this error.

The W83627DHG has some power managements bits to power down individual
logical devices. These are called `* Power Down`. Counterintuitively and
in contrast to `Immediate Power Down` (bit to power down the whole chip),
these bits are set when the respective logical device is powered.
Unfortunately, our ACPI code set them wrong which led to disabled
devices after a S3 suspend/resume. Adding an option how to set the PM
bits and setting them to zero for the W83627DHG, corrects it.
Tested with kontron/ktqm77.

With USBDEBUG selected, PCI EHCI controller's device_operations
.read_resources is replaced with pci_ehci_read_resources() call,
which in turn will replace the device_operations .set_resources call.
The replacement for .set_resources reconfigures usbdebug driver side,

controller (GbE). The layout of the flash ROM (and other information) is
kept in the so called Intel Firmware Descriptor (IFD). If we only want
to build coreboot to update the BIOS section, all we need is the flash
layout.
This patch adds the option to specify the flash layout in the
mainboard's Kconfig, and thus, to build without the real IFD. However,
with such a build, one has to make sure that the IFD section on the
flash ROM won't be written over (nor any other section that hasn't been
included by coreboot). A patch to write selected sections of a flash ROM
with IFD has been sent to the flashrom mailing list [1].
