Above doesn't look right. I think it could be written "if(gen>=11) {...} 
else if(gen>=9){...". Now it looks support for planar formats on ICL is 
totally skipped. As is inside skl_plane_has_planar(..) there's check if 
running on ICL no planar support is available but it is only until 
planar support for ICL is patched in. I suspect you are going to need 
icl_primary_formats[] as well as icl_pri_planar_formats[] in similar way 
as on SKL. It is similar issue below with changes for intel_sprite.c
