ARM: mxs: use auxdata to attach mxsfb_platform_data
Use auxdata to attach mxsfb_platform_data for imx23-evk and imx28-evk. We take this as a temporary solution for removing those board files, and it should be updated to use common bindings for struct fb_videomode when it becomes available. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
