ARM: dts: vf610-colibri: enable DCU framebuffer

Enable DCU framebuffer driver for display output. Define VGA as
native resolution which is selected by default. Also there are
some other timings defined which are often used with our evaluation
board. These are selectable through a video=dcufb:... kernel
argument. However, for final products, its recommended to create an
altered device tree which contains only display timings which are
supported by the display in use.
