MLK-18767: drm: imx: dcss: fix vblank timed out warning
The following commit:
f9a03b3 - MLK-17925: drm: imx: dcss: fix tearing
introduced a regression because we does not send VBLANK event if context
loader was not flushed. But this condition is always met immediately
after enabling the CRTC. Hence, when 30FPS modes are selected, it is
possible to exceed the 50ms vblank timeout if the first event is not
sent. That's because 2 x 0.33ms > 50ms. This does not happen for 60fps
modes though.
This patch will force sending the first vblank event even if the context
loader is not completely flushed.
