cassini/niu/sun*: Move the Sun drivers
Moves the Sun drivers into drivers/net/ethernet/sun/ and make
the necessary Kconfig and Makefile changes.
Oliver Hartkopp <socketcan@hartkopp.net> suggested removing the
sun* prefix on the driver names. This type of change I will
leave up to the driver maintainers.
