Only build fb_logo.c if CONFIG_LOGO has been selected. Otherwise
provide empty implementations of the contained interfaces and avoid

IMHO, *sometimes* it makes sense to not use #ifdef and code it instead like this:
  			if (IS_ENABLED(CONFIG_LOGO) &&
			    !strcmp(options, "center"))
...
That way the compiler will optimize that code away as well, but in
addition it will compile-check that you have correct coding independend
if CONFIG_LOGO is set or not.

  			continue;
  		}

  		if (!strncmp(options, "logo-count:", 11)) {
  			options += 11;
+#ifdef CONFIG_LOGO
  			if (*options)
  				fb_logo_count = simple_strtol(options, &options, 0);
+#endif

same here.
