ARM: dts: imx28-evk: Convert to the new display bindings
imx28-evk board has a Seiko 43WVF1G parallel display. Instead of hardcoding the display timings in the device tree, use the "sii,43wvf1g" compatible instead. This aligns with the new mxsfb bindings scheme documented at: Documentation/devicetree/bindings/display/mxsfb.txt Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
