I would go a step further and just allow GTT domain on ASICs != CARRIZO
| STONEY.
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.

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

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.
