Subject: exynos5420: fix compilation without parade video

Not all exynos 5420 based devices with an LCD also have a parade LVDS
bridge. So make sure compilation doesn't break if CONFIG_LCD is enabled
and CONFIG_VIDEO_PARADE is not.

As a side-effect move the parade functions from the exynos system header
file to its own file.
