drm/sun4i: layer: Remove redundant zpos initialisation

Browse Source 
The sun4i KMS driver will call drm_plane_create_zpos_property() with an
init value depending on the plane type.

Since the initial value wasn't carried over in the state, the driver had
to set it again in sun4i_backend_layer_reset().
However, the helpers have been adjusted to set it properly at reset, so
this is not needed anymore.
