Revert "drm/bridge: lt9611: Do not generate HFP/HBP/HSA and EOT packet"
This reverts commit 8ddce13ae696 ("drm/bridge: lt9611: Do not generate
HFP/HBP/HSA and EOT packet") to fix display regression on the Dragonboard
845c (SDM845) devboard.
There's a mismatch on the real action of the following flags:
- MIPI_DSI_MODE_VIDEO_NO_HSA
- MIPI_DSI_MODE_VIDEO_NO_HFP
- MIPI_DSI_MODE_VIDEO_NO_HBP
which leads to a non-working display on qcom platforms.
