Add PNR info and remove "Unity" from emc prio, path_checker and hardware_handler.
Unity series does not support PNR mode, just ALUA.

DROP this one, path_checker should be emc.

OK, thanks. In general, I think we shouldn't include too detailed
vendor-specific information in our documentation, as it's too prone to
be wrong or outdated.
