drm/exynos: gsc: add device tree support and remove usage of static mappings

Browse Source 
This patch adds device tree support for exynos_drm_gsc. This patch
also fixed build issue on non-Exynos platforms, thus dependency on
!ARCH_MULTIPLATFORM can be now removed. The driver cannot be used
simultaneously with V4L2 Mem2Mem GScaller driver thought.
