So I'm a bit at a loss here: whether I should totally remove VIN1 device if I'm going to add Ether device, or add a BOCK-W specific submenu to Kconfig, or add driver specific #ifdef's in the code to disable VIN1 if sh_eth driver is enabled?...

My preference, in order is: * Remove VIN1 (is it used?) * Kconfig-foo * #ifdef nastiness
