Subject: [PATCH] drm/rockchip: vop: fix some register define error for px30

1. interrupt register define error lead to enable interrupt failed;
2. px30 unsupport hdmi output;
3. there are some hardware designed bug, we must swap win2 gate and
   enable offset, otherwise will appear vop iommu pagefault.
