I am afraid having 'gpio-mux' and 'gpio-multiplexer' would create too 
many what-were-they-thinking moments for any unfortunate reader so I 
would rather choose something else. Can we just call it 'gpio-cascade' 
without referral to the underlying mux? Maybe at somepoint in future 
something else could be used in its place too.
