mx51evk: Fix build error when CONFIG_VIDEO is disabled
The inclusion of LCD patch into mx51evk breaks the build when CONFIG_VIDEO is disabled. Fix this by splitting the video related stuff to a new file. Also rename the function lcd_iomux to setup_iomux_lcd to make the namings aligned with the other iomux functions.
