Subject: [PATCH] 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.
