TVE200's interrupt is configured as rising-edge. On the D-Link DIR-685,
this can stop interrupt delivery after the first vertical interrupt,
causing vblank and page-flip timeouts and delaying framebuffer console
startup.
The vertical interrupt can remain pending after acknowledgment. Use
level-high triggering so the pending condition is delivered again
without requiring another edge.
