Subject: [PATCH v2 2/2] drm: Make fbdev emulation select FB_CORE instead of depends on FB

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

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.

Changes in v2:
- Make CONFIG_DRM_FBDEV_EMULATION to select FB_CORE (Thomas Zimmermann).
