The zpos of exynos plane is just the index of overlay of exynos fimd or
exynos hdmi. 0 zpos means first overlay and 1 zpos means second overlay.
It isn't the priority value but higher zpos will have higher priority
generally.
A negative value -1 is defined to special value. A exynos crtc should
use one overlay and -1 zpos means the overlay that crtc uses.
Thanks.
