ARM: S3C64XX: Move SmartQ LCD control platform definition to shared file
This shares the common LCD control platform definition used in the SmartQ 5 and 7. This also corrects it as a GPIO bitbanged SPI device instead of an I²C one, which was wrong. Signed-off-by: Maurus Cuelenaere <mcuelenaere@gmail.com> Signed-off-by: Ben Dooks <ben-linux@fluff.org>
