drm/amd/display: fix flickering caused by S/G mode
commit 08da182175db4c7f80850354849d95f2670e8cd9 upstream.
Currently, on a handful of ASICs. We allow the framebuffer for a given
plane to exist in either VRAM or GTT. However, if the plane's new
framebuffer is in a different memory domain than it's previous
framebuffer, flipping between them can cause the screen to flicker. So,
to fix this, don't perform an immediate flip in the aforementioned case.
