Some hardware may not support standard 64x64 cursors. Add
a drm cap to query the cursor size from the kernel. Some examples
include radeon CIK parts (128x128 cursors) and armada (32x64 or 64x32).
This allows things like device specific ddxes to remove asics specific
logic and also allows xf86-video-modesetting to work properly with hw
cursors on this hardware. Default to 64 if the driver doesn't specify
a size.

CIK parts are 128x128, older parts are 64x64.

Use new drm caps. This allows hw cursors to work
correctly on gpus with non-64x64 cursors.

The patches look good, but what's your plan for dealing with other KMS
apps such as Wayland compositors (weston is also affected by this, I
assume so is gnome-shell, maybe more)? I was thinking it might be good
to have a backup plan in the kernel, e.g. copying from the BO passed in
by userspace to a different BO if the former doesn't match the hardware
size.

I think the easiest fix would be for them to fix up support similarly
to what I did for xf86-video-modesetting so they are ready to go once
distros start enabling them by default. Adjusting the image on the
fly in the kernel seems a like pain.
