video: sunxi: de2: fix SimpleFB node creation when DE2 not probed
Sometimes when a monitor without EDID information is plugged, the DE2
won't be probed (because of lack of timing information), but the HDMI
node is probed, thus a SimpleFB node with invalid information will be
populated.
Also detect whether DE2 is probed when creating SimpleFB node.
Fixes: be5b96f0e411 ("sunxi: setup simplefb for Allwinner DE2")
