From: Emanuele Ghidoli <emanuele.ghid...@toradex.com>
The component datasheet recommends, to reduce power consumption,
transitioning to LP mode on every video line.
Enable the MIPI_DSI_MODE_VIDEO_NO_HFP and MIPI_DSI_MODE_VIDEO_NO_HBP
flags so that the bridge can enter LP mode during the horizontal front
porch and back porch periods.
