Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ 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.
