[PATCH] Enable MIPI filtering by DT on i.MX8M*

[Krzysztof Hałasa]

In addition to raw image data, certain MIPI sensors send additional
information like NULL packets or "embedded 8-bit non-image data".
Without DT (data type) filtering, these packets end up in the frame
buffer, corrupting it.

Tested on i.MX8MP with IMX290 sensor.
