[PATCH v2 3/8] drm/exynos: fixed vflip, hflip case at the same time.

[Eunchul Kim]

Changelog v2:
This patch added EXYNOS_DRM_FLIP_BOTH enum value for warnning.

Changelog v1:
This patch fixed vflip, hflip at the same time. If we want to change 180 degree 
about buffer,
then we can use h,vflip or 180 degree. we supports 180 degree using h,vflip.
but we make error handling in this case. so, fixed it.
