If the vblank IRQ happens to trigger during that time, we will prematurely signal the atomic commit completion to userspace, which causes tearing when userspace re-uses a framebuffer we haven't managed to flip away from yet.

This means that the driver doesn't have to keep track of that. Also use the drm_fb_helper functions directly.

The new drm_atomic_helper_setup_commit in 4.15 expects that blocking commits have completed flipping before the commit_tail returns. This must be ensured by calling wait_for_vblanks or wait_for_flip_done, where flip_done might do a less agressive wait, which is fine for imx-drm.
