drm/rockchip: vop2: clear afbc en and transform bit for cluster window at linear mode
The enable bit and transform offset of cluster windows should be
cleared when it work at linear mode, or we may have a iommu fault
issue on rk3588 which cluster windows switch between afbc and linear
mode.
As the cluster windows of rk3568 only supports afbc format
so is therefore not affected.
