drm/msm/sde: add topology management properties
Need to expose connector properties for user interaction with
dynamic hardware resource mapping to drm object topologies.
Expose topology_control property on each connector to allow user
control reservation behavior. An immutable topology_name
property is exposed on each connector to allow user to query
active use case driver chose.
