Sascha Hauer de4a4c8f64 drm/rockchip: vop2: Register Esmart0-win0 as primary plane 
Esmart0-win0 could serve as primary plane, so mark it as such. On
RK3568 this window will never be used as primary plane, because the
three windows at the beginning of the rk3568_vop_win_data[] array
will be used. On RK3566 however, two of the windows at the beginning
of the rk3568_vop_win_data[] array cannot not be used due to hardware
limitations, so without this patch we end up with CRTCs without primary
planes when multiple VPs are active.
