drm: Rename drm_mode_object_get()

Subsequent patches will introduce reference counting APIs that are more consistent with similar APIs throughout the Linux kernel. These APIs use the _get() and _put() suffixes and will collide with this existing function. Rename the function to drm_mode_object_add() which is a slightly more accurate description of what it does. Also the kerneldoc for this function gives an indication that it's badly named because it doesn't actually acquire a reference to anything.
