drm/amd/display: wait for test pattern after when all pipes are programmed
[why]
Currently we wait for test pattern after each pipe is programmed. For
ODM combined scenario it will cause test pattern is shown on only half
screen for 1 frame. This is not desirable.
[how]
No wait between odm pipe programming, only wait after all pipes are
programmed.
