*sonic/natsemi/ns83829: Move the National Semi-conductor drivers

Move the National Semi-conductor drivers into drivers/net/ethernet/natsemi/
and make the necessary Kconfig and Makefile changes.  Also moved the 8390
(National Semi-conductor) devices as a sub-menu of National Semi-conductor
devices.

- moved the ibmlana driver as well into this directory since it is a
  "SONIC" driver
