Used to handle kernel events specific to the Exynos platform.
Currently only G2D events are handled.

Some compilers (like the Oracle Studio), require that the function
declaration must be annotated with the same visibility attribute as the
definition. As annotating functions with drm_public is no longer
required just remove the macro.

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.

this patch adds libdrm_exynos helper layer that inclues some intefaces
for exynos specific gem and virtual display driver and also adds exynos
module name to modtest and vbltest.
Changelog v2:
- fixed exynos broken ioctl.
the pointer of uint64_t *edid should be removed.
- removed unnecessary definitions.
- added drm prime interfaces.
