Subject: drm/exynos: rotator: Fix DRM_MODE_REFLECT_{X,Y} interpretation
Git-commit: 1b0966c3e951da6ae523c4e954b1f43b22927948
Patch-mainline: v4.18-rc4
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Horizontal (DRM_MODE_REFLECT_Y) and vertical (DMR_MODE_REFLECT_Y) flip
were swapped in Rotator driver. Fix this by swapping code for interpreting
them.
