The 'de-active' and 'pixelclk-active' DT properties are evaluated by of_parse_display_timing() called from of_get_drm_display_mode(), but later lost in the conversion from videomode.flags to drm_display_mode.flags. Use an open coded version of of_get_drm_display_mode() to get access to these flags and make sure they are passed on to the ipu-di driver.
Changes vs. v2:
- removed patches which have already been applied
- created a drm_bus_flags_from_videomode() helper to prevent code duplication as suggested by Philipp Zabel
Changes vs. v1:
- rebased on top of https://patchwork.kernel.org/patch/9113791/ as per Philipp Zabel's request

Maybe a stupid question, but why does i.MX even allow video timings to be specified in DT instead of going through panel drivers like everyone else?
