[PATCH] drm/mgag200: Fix VBLANK interrupt handling

[Thomas Zimmermann]

Fix support for VBLANK interrupts on G200ER, G200EV and G200SE, which
use a slightly different implementation than the others. The original
commits forgot to update the custom helpers when adding interrupt
handling for VBLANK events.
