drm: fb_helper: fix CONFIG_FB dependency

Browse source 
With CONFIG_FB=m and CONFIG_DRM=y, we get a link error in the fb helper:

aarch64-linux-ld: drivers/gpu/drm/drm_fb_helper.o: in function `drm_fb_helper_alloc_fbi':
(.text+0x10cc): undefined reference to `framebuffer_alloc'

Tighten the dependency so it is only allowed in the case that DRM can
link against FB.

Fixes: f611b1e762 ("drm: Avoid circular dependencies for CONFIG_FB")
