Subject: [RFC PATCH 4/4] drm: Make fbdev emulation depend on FB_CORE instead of FB

Now that the fbdev core has been split in FB_CORE and FB, make DRM fbdev
emulation layer to just depend on the former.

This allows to disable the CONFIG_FB option if is not needed, which will
avoid the need to explicitly disable all the legacy fbdev drivers.
