drm/exynos: fimd: fix broken dp_clock control

Commit 1feafd3afd294b03dbbedb8e8f94e0c4db526f10 ("drm/exynos: add
exynos5420 support for fimd") add support for Exynos 5420 SoC, but it
broke enabling display clock feature because of incorrect condition
check. This patch fixes it, so display is working again on platforms
requiring display clock control (i.e. Exynos5250-based SNOW platform).
