msm: camera: ife: Configure epoch to exactly half of the frame

Some customers have sensor mode with more blanking width.
Due to this, time is not sufficient for applying
setting thus resulted in frame drops.
To avoid this situation, epoch is calculated on complete
frame and configured at half the frame.
