As DM_ETH is required for all network drivers, it's now safe to remove the non-DM_ETH support code. Doing this removes some board support code which was also unused. Finally, this removes some CONFIG symbols that otherwise needed to be migrated to Kconfig, but were unused in code now. Signed-off-by: Tom Rini <trini@konsulko.com>
