F15tn: Modify devicetree to fix S3 resume
The way that devicetree.cb was configured for the family 15tn boards was doing... interesting things to the video device initialization. This was causing S3 resume to fail. There is a disconnect between how the devicetree should be configured if there are multiple HT links on the CPU and how it's configured if there's only one HT link. These platforms were set up as if they had multiple HT links, which was causing duplicate instances of devices in the device list. The scan for the IO Hub was removed from the northbridge code which isn't a problem for F15tn devices.
