lm(4) driver from NetBSD adapted for sysctl interface.

The lm driver provides support for the National Semiconductor LM series
hardware monitors and register compatible chips. It supports LM78,
LM78-J, LM79, Winbond W83697HF, W83627HF, W83781D and W83782D chips.

Tested and ok'ed by millert@ and henning@.
