drm/komeda: plane: Remove redundant color encoding and range initialisation

The komeda KMS driver will call drm_plane_create_color_properties() with
a default encoding and range values of BT601 and Limited Range,
respectively.

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.
