drm/exynos: make zpos property immutable
We already set each plane zpos at init, after that changes to zpos are not expected. This patch turns zpos into a read-only property so now it is impossible to set zpos. Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Inki Dae <inki.dae@samsung.com>
