drm: Make FB_CORE to be selected if DRM fbdev emulation is enabled

Now that fbdev core has been split in FB_CORE and FB, make the DRM symbol
to select the FB_CORE option if the DRM fbdev emulation layer is enabled.

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