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.
