drm/atomic: Add support for mouse hotspots
Atomic modesetting code lacked support for specifying mouse cursor
hotspots. The legacy kms DRM_IOCTL_MODE_CURSOR2 had support for setting
the hotspot but the functionality was not implemented in the new atomic
paths.
Due to the lack of hotspots in the atomic paths userspace compositors
completely disable atomic modesetting for drivers that require it (i.e.
all paravirtualized drivers).
This change adds hotspot properties to the atomic codepaths throughtout
the DRM core and will allow enabling atomic modesetting for virtualized
drivers in the userspace.
