For non architected timers, we want to be able to convert the timers as 
modules.

That's an on-going work [1].

Your series assumes we won't convert that into modules, so you do the 
conversion to builtin. But actually, there is a slow move to module 
conversion.

However, given a clockevent can not be unregistered, the 
'suppress_bind_attrs' flag makes sense for those registering one.
