drm/omapdrm: Switch private_obj initialization to atomic_create_state

Browse Source 
The omapdrm driver relies on a drm_private_obj, that is initialized by
allocating and initializing a state, and then passing it to
drm_private_obj_init.

Since we're gradually moving away from that pattern to the more
established one relying on a atomic_create_state implementation, let's
migrate this instance to the new pattern.
