ewrk3/tulip: Move the DEC - Tulip drivers
Move the DEC - Tulip driver into drivers/net/ethernet/dec/tulip/
and make the necessary Kconfig and Makefile changes.
The Digital Equioment (DEC) driver ewrk3 was moved into
drivers/net/ethernet/dec/ and the remaining drivers (Tulip)
were moved into drivers/net/ethernet/dec/tulip/
