Subject: drm/komeda: plane: Remove redundant color encoding and range
 initialisation
Git-commit: e026f2880235025643fd7d68dbe972d544d7f44f
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

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.
