*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
