[PATCH 5/6] drm/virtio: Create mouse hotspot properties on cursor planes

[Zack Rusin]

From: Zack Rusin <za...@vmware.com>

Atomic modesetting got support for mouse hotspots via the hotspot
properties. Drivers need to create those properties on cursor planes
which require the mouse hotspot coordinates.

Add the code creating hotspot properties and port away from old legacy
hotspot API. The legacy hotspot paths have an implementation that works
with new atomic properties so there's no reason to keep them and it
makes sense to unify both paths.
