util/sconfig: Get rid of nextdev member in struct device

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=80081934
TEST=Verified that static.c generated for all boards built by abuild
is same with and without this change.
