This reverts commit [1] 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.

The boards broken by [1] are used in production by different parties
since 5.10, breaking them doesn't seem more acceptable than breaking the
new out-of-tree iMX8m hardware.
The MX8M is also in-tree, so this does not apply.
