[PATCH 11/23] drm/imx: ipuv3-plane: Remove redundant zpos initialisation

[Maxime Ripard <maxime@cerno.tech>]

The imx 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 ipu_plane_state_reset(). However, the helpers have
been adjusted to set it properly at reset, so this is not needed
anymore.
