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.
