libdrm: add exynos drm support

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.
  this feature is used to share a buffer between drivers or memory managers
  and for this, please, refer to below links:
