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.
