til_setup: introduce til_setup_t
Preparatory commit for providing a res_setup type to replace void*. The impetus for this isn't just pursuit of less void*, but primarily implementing setup freeing by embedding this struct into the private setup types. An alternative method of adding setup freeing would have been to introduce something like til_module_t.free_setup(). But that would require having the til_module_t on hand, and the whole setup machinery is more generalized than til_module_t anyways. This way anything can simply embed the struct in their private setup instance and return the pointer to that in *res_setup. They should always be able to find their containing struct's offset from the til_setup_t* they returned. Either by using container_of(), or simply placing it at the start of the private setup struct.
