Rene Herman bc033c9b5f pnp: add pnp_build_option() to the API
The subsequent AD181x quirk patch would like this as part of the API.
pnp_register_dependent_option() adds to the same dependent chain the quirk is
walking which is fairly unclean.  This enables a private option chain build
which it can then just add onto the end when done.
