drm/rockchip: Fix crtc_state->event signalling It's not permissible to look at plane->state from interrupt context, since doing that would need the irq handler to acquire the plane->mutex lock. The other problem is that if we pipeline updates using the new nonblocking atomic helpers new state gets commit before the irq handler fires, resulting in a lost event. Fix both issues by caching the necessary values in vop_win, protected by dev->event_lock.
