[U-Boot] [PATCH 2/2 v3] exynos5420: fix compilation without parade video

[Sjoerd Simons]

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.

 Changes since V2: Take the opportunity to move parade_init to it's own include
                   file. As requested by Minkyu Kang
