amdgpu: Always allocate bo with modifier on GFX9+.
For virtualization purposes we always want to have a modifier. With
radeonsi that means allocating with modifiers. This has the
complication that the structure of modifiers isn't trivial.
Three implementation options:
1) Add dri-flag to create bo with valid modifier
2) Figure out scanout capable modifiers in minigbm
3) Take scanout capable modifiers from kernel.
3 is an issue because the card node is often behind a video group
on desktop linux and we don't want to create something that won't
work on desktop linux.
For 2 I figured out that the structure is actually fairly simple if
we assume that the DRI driver doesn't provide useless modifiers.
For 1 we'd end up having to do the same work as 2 + define the
DRI interface + maybe have to deal with older somewhat buggy kernels.
So I ended up selecting 2.
Note that this also removes CURSOR usage in the old path with DRI
On AMD we only allow linear for the cursor so this gets handled
in the linear path.
