drm/exynos: gsc: fix wrong bitwise operation for swap detection
The bits for rotation are not used as exclusively. So GSC_IN_ROT_270 can not be used for swap detection. The definition of it is same with GSC_IN_ROT_MASK. It is enough to check GSC_IN_ROT_90 bit is set or not to check whether width / height size swapping is needed.
