[PATCH] of: videomode: Fix module loading problem

[Mohsin Kazmi <mohsin_kazmi@mentor.com>]

This patch adds the support load as a module of_videomode.c which is required by parallel display.
I have encountered the following problem.

imx_parallel_display: Unknown symbol of_get_video_mode (err 0)
insmod: can't insert 'imx-parallel-display.ko': unknown symbol in module, or unknown parameter

of_get_video_mode() is available in of_videomode.c but it couldn't loaded and gave the following error.

of_videomode: Unknown symbol of_property_read_u32_array (err 0)
modprobe: can't load module of_videomode (kernel/drivers/of/of_videomode.ko): unknown symbol in module, or unknown parameter

I have discussed this with Dmitry Eremin-Solenikov. He told me to do so as in this patch and it works.
