Use an explicit callback name so that multiple instances of this do not
result in a:
redefinition of '_input_callback__longpress_cb'
error. This used to work when it was using unique generated wrappers,
but now it needs an index in the callback name.
Use it in one of the API tests as well, just in case.

Add a void *user_data pointer to the input callback structure. This is
useful for driver to get back the driver data structure and avoid
defining wrapper functions.

This driver really needs a device associated with it for the
syncronization bit to make sense, and since the argument is DT_PARENT it
will get it all the time, so no changes in practice, but this should
have been using the normal macro anyway.
