Fix confusion between pin number and AF number #254

Unfortunately, I got lost in the macro depths when working on the gpio typestates and a small but significant bug sneaked in. When requesting pin PAx to AFy, this erroneously configured PAy to get the requested output type (push-pull or open-drain). This is fixed now.
