exynos: Don't use DRM_EXYNOS_GEM_{MAP_OFFSET/MMAP} ioctls
The ioctl DRM_EXYNOS_GEM_MAP_OFFSET and DRM_EXYNOS_GEM_MMAP are removed from the linux kernel. This patch modifies libdrm and libkms to use drm generic ioctls instead of the removed ioctls. v2: The original patch was erroneous. In case the MODE_MAP_DUMB ioctl failed it would return the retvalue as a void-pointer. Users of libdrm would then happily use that ptr, eventually leading to a segfault. Change this to return NULL in that case and also restore the previous behaviour of logging to stderr. The other error was that 'bo->vaddr' was never filled with the mapped buffer address. Hence exynos_bo_map still returned NULL even if the buffer mapping succeeded.
