[PATCH] drm: create struct drm_object_properties and use it

From: Paulo Zanoni <paulo.r.zanoni at intel.com>
For now, only connectors have it. In the future, all objects that need
properties should use it. Since the structure is referenced inside
struct drm_mode_object, we will be able to deal with object properties
without knowing the real type of the object.

Fixed.
