Now that chips and devices are treated differently and the device tree actually contains only devices, next and nextdev are exactly the same for all devices in the tree. This change gets rid of nextdev pointer and updates all uses of nextdev to next. BUG=b:80081934 TEST=Verified that static.c generated for all boards built by abuild is same with and without this change.
