[NET]: Fix WAN routers kconfig dependency.
Currently WAN router drivers can be built in-kernel while the register/unregister_wan_device interfaces are built as modules. This causes: drivers/built-in.o: In function `cycx_init': cycx_main.c:(.init.text+0x5c4b): undefined reference to `register_wan_device' drivers/built-in.o: In function `cycx_exit': cycx_main.c:(.exit.text+0x560): undefined reference to `unregister_wan_device' make: *** [.tmp_vmlinux1] Error 1 The problem is caused by tristate -> bool conversion (y or m => y), so convert WAN_ROUTER_DRIVERS to a tristate so that the correct dependency is preserved.
