drm/exynos: mixer: Fix color format setting

Browse source 
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.
