[PATCH 10/23] drm/exynos: plane: Remove redundant zpos initialisation

[Maxime Ripard]

The exynos KMS driver will call drm_plane_create_zpos_property() with an
init value depending on the plane purpose.

Since the initial value wasn't carried over in the state, the driver had
to set it again in exynos_drm_plane_reset(). However, the helpers have
been adjusted to set it properly at reset, so this is not needed
anymore.
