nvidia: Clean up t210 MBIST WAR handling

Browse Source 
On k4.4 and earlier, t210 MBIST workaround was handled with notifier
callbacks within the drivers. Remove all such calls to the functions
slcg_register_notifier and slcg_unregister_notifier.

Also remove the functions nvhost_pd_slcg_install_workaround and
nvhost_pd_slcg_remove_workaround which ultimately call the
slcg_register_notifier and slcg_unregister_notifier functions
respectively.
