  To: dri-devel; +Cc: linux-samsung-soc, inki.dae, sw0312.kim, yj44.cho

The exynos fimd provides video type selection bits from system register
but exynos3 series don't has it, so needs has_vtsel flag and we can
distinguish whether set video type selection bits.

Changelog from v1:
- rebase on latest exynos-drm-next branch
- add has_vtsel for exynos4415
