drm/rockchip: vop2: set half_block_en bit in all mode
At first we thought the half_block_en bit in AFBCD_CTRL register only work in afbc mode. But the fact is that it control the line buffer in all mode(afbc/tile/linear), so we need configure it in all case. As the cluster windows of rk3568 only supports afbc format so is therefore not affected.
