drm: Introduce DRM_CLIENT_CAP_CURSOR_PLANE_HOTSPOT
Virtualized drivers place additional restrictions on the cursor plane
which breaks the contract of universal planes. To allow atomic
modesettings with virtualized drivers the clients need to advertise
that they're capable of dealing with those extra restrictions.
To do that introduce DRM_CLIENT_CAP_CURSOR_PLANE_HOTSPOT which
lets DRM know that the client is aware of and capable of dealing with
the extra restrictions on the virtual cursor plane.
Setting this option to true makes DRM expose the cursor plane on
virtualized drivers. The userspace is expected to set the hotspots
and handle mouse events on that plane.
