fbdev/core: Remove empty internal helpers from fb_logo.c

Remove the two empty helpers for the case the CONFIG_FB_LOGO_EXTRA
has not been set. They are internal functions and only called once.
Providing empty replacements seems like overkill. Instead protect
the call sites with a test for CONFIG_FB_LOGO_EXTRA.
