[PATCH v3 2/4] drm/rockchip: remove the unsupported format of vop2 cluster window

[Andy Yan]

From: Andy Yan <andy.yan at rock-chips.com>

The cluster windows on vop2 doesn't support linear yuv
format(NV12/16/24), it only support afbc based yuv
format(DRM_FORMAT_YUV420_8BIT/10BIT), which will be
added in next patch.

Fixes: 604be85547ce ("drm/rockchip: Add VOP2 driver")
Signed-off-by: Andy Yan <andy.yan at rock-chips.com>

Changes in v3:
- make it a split patch
