drm/exynos: resolve infinite loop issue on multi-platform
This patch resolves temporarily infinite loop issue incurred when Exynos drm driver is enabled and multi-platform kernel is used by registering Exynos drm device object only in case of Exynos SoC. So this patch will be replaced with more generic way later. Signed-off-by: Inki Dae <inki.dae@samsung.com>
