Use drm cursor ioctls instead of exynos-specific hacks.

The exynos display controllers (FIMD, MIXER) have special requirements
for scanning out small buffers. In particular, the ones used for cursors.

Now that the exynos drm driver supports cursor ioctls that implement the
required buffer padding, we can remove the special cursor handling from the
DDX and just use these ioctls directly.
