drm/rockchip: vop2: clear afbc en and transform bit for cluster window at linear mode

Browse Source 
[ Upstream commit 20529a68307feed00dd3d431d3fff0572616b0f2 ]

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.
