6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jonas Karlman <jonas@xxxxxxxxx>
[ Upstream commit 4d49d87b3606369c6e29b9d051892ee1a6fc4e75 ]
Add missing call to crtc reset helper to properly vblank reset.
Also move vop2_crtc_reset and call vop2_crtc_destroy_state to simplify
and remove duplicated code.
Fixes: 604be85547ce ("drm/rockchip: Add VOP2 driver")
