I can't see a good reason we should still have any limitation here, VRAM
doesn't have any advantage any more as far as I know.
Well, if VRAM is available we want to make sure someone uses it
otherwise it's just wasted.

Well it still gets used when it's free. So now problem at all here.

We should just not force anything into VRAM or GTT any more if it's technically not necessary.

      drm/amdgpu: try allowed domain when pin framebuffer failed.



      [WHY&HOW]



      in some scenarios, the allocate memory often failed. such as do hot plug 
or play games.

      so we can try allowed domain, if the preferred domain cannot allocate 
memory.
