drm/exynos: gsc: Fix DRM_MODE_REFLECT_{X,Y} interpretation
Horizontal (DRM_MODE_REFLECT_Y) and vertical (DMR_MODE_REFLECT_Y) flip were swapped in GScaler driver. Fix this by swapping code for interpreting them. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
