Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

The SYSCTL_NODE macro defines a list that stores all child-elements of

reason why it shouldn't be static.

The SMCWUSBG is a zyd(4) device, not an uath(4) device. Remove from the

The SMCWUSBG is a zyd(4) device, not an uath(4) device. Remove from the
latter.

It appears that the addition to uath(4) came in through PR kern/135009,
which had tested another device, the SMCWUSBTG2, successfully with uath(4)
and included the SMCWUSBG as it "has the same chipset". I can find no
other evidence that these two do actually share the same chipset. Moreover,
Linux treats the SMCWUSBG as a zyd(4) device also.

This reverts r223537.
