MLK-17647: drm: imx: dcss: fix the flip_done timed out problem

The commit:

44c45128 - MLK-17634-1: drm: imx: dcss: send vblank event from ISR

made some changes related to vblank handling. However, it looks like
they were not robust enough and, sometimes, the flip events are not
sent. This happens only when playing videos over Weston.

This patch, effectively, reverts those changes.
