drm/exynos: Remove non-DT support in exynos_hdmi
Since commit 383ffda2fa ("ARM: EXYNOS: no more support non-DT for EXYNOS SoCs"), Exynos platform is DT only. Hence remove all the conditional macros and make the driver DT only. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Inki Dae <inki.dae@samsung.com>
