drm/exynos: mixer: Fix color format setting
Fix color format decision based on height(pixels). According to CEA-861-E: "High Definition (HD) - A CE video format that, inclusively, has between 720 to 1080 active vertical lines (Vactive) lines per video frame." Tested on Odroid-U3 with Exynos 4412 CPU, kernel next-20181128 using modetest. Signed-off-by: Christoph Manszewski <c.manszewski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
