Peter Ujfalusi a7631c4b98 drm/omap: Filter displays mode based on bandwidth limit
If we have memory bandwidth limit configured, reject the modes which would
require more bandwidth than the limit if it is used with one full
resolution plane (most common use case).

This filtering is not providing full protection as it is possible that
application would pick smaller crtc resolution with high resolution planes
and down scaling, or can enable more smaller planes where the sum of their
bandwidth need would be higher than the limit.

This patch only allows us to filter out modes which would need more
bandwidth if they were used with one full screen plane.
