video: s3c-fb: move enabling channel for window
This patch moves enabling channel for window, because there should be enabling channel before enabling window. If the sequence is reversed, it makes the problem in displaying images to lcd panel. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
