[PATCH 09/23] drm/komeda: plane: Remove redundant zpos initialisation

[Maxime Ripard]

The komeda KMS driver will call drm_plane_create_zpos_property() with an
init value of the plane index.

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