[PATCH v2 6/8] drm/vc4: Call drm_atomic_helper_fake_vblank() in the commit path

[Boris Brezillon]

Mimic what is done in drm_atomic_commit_tail() and call
drm_atomic_helper_fake_vblank() so that VBLANK events are faked
when the drm_crtc_state.no_vblank is true. Will be needed when we'll
add support for the transposer block.
