While the mdp5_plane_install_properties() function calls drm_plane_create_zpos_property() with an initial value of 1, mdp5_plane_reset() will force it to another value depending on the plane type. Fix the discrepancy by setting the initial zpos value to the same value in the drm_plane_create_zpos_property() call.
