mb/*/*: Harmonise FD and devicetree on boards featuring ICH7
On some boards the devicetree and Function Disable register did not
match. In this case the FD values are put in the devicetree as these
were the values that were actually used in practice.
A complete devicetree will make it easier to automatically disable
devices in ramstage.
