Ask the IPU display interface, via ipu_di_adjust_videomode(), to
adjust a video mode to meet any DI restrictions. The function takes
a subsystem independent videomode, so the drm_display_mode must be
converted to videomode first, and then the adjusted mode converted
back to a drm_display_mode.

What is the reason to use videomode (apart from it being subsystem
independent)?  Do we forsee implementation of other output subsystems
for the IPU?
