Subject: [PATCH AUTOSEL 6.6 127/294] drm/rockchip: vop2: Add uv swap for cluster window

From: Andy Yan <andy.yan@...k-chips.com>

[ Upstream commit e7aae9f6d762139f8d2b86db03793ae0ab3dd802 ]

The Cluster windows of upcoming VOP on rk3576 also support
linear YUV support, we need to set uv swap bit for it.

As the VOP2_WIN_UV_SWA register defined on rk3568/rk3588 is
0xffffffff, so this register will not be touched on these
two platforms.
